(CNN) -- A lawsuit has been filed claiming that the iconic Led Zeppelin song "Stairway to Heaven" was far from original. 

The suit, filed on May 31 in the United States District Court Eastern District of Pennsylvania, was brought by the estate of the late musician Randy California against the surviving members of Led Zeppelin and their record label. The copyright infringement case alleges that the Zeppelin song was taken from the single "Taurus" by the 1960s band Spirit, for whom California served as lead guitarist. 

"Late in 1968, a then new band named Led Zeppelin began touring in the United States, opening for Spirit," the suit states. "It was during this time that Jimmy Page, Led Zeppelin's guitarist, grew familiar with 'Taurus' and the rest of Spirit's catalog. Page stated in interviews that he found Spirit to be 'very good' and that the band's performances struck him 'on an emotional level.' " 

One of the causes of action for the suit is listed as "Falsification of Rock N' Roll History" and the typeface in the section headings of the filing resembles that used for Led Zeppelin album covers. According to claims in the suit, "Parts of 'Stairway to Heaven,' instantly recognizable to the music fans across the world, sound almost identical to significant portions of 'Taurus.' " 

The estate is seeking court ordered damages and writing credit for California, born Randy Craig Wolfe. Part of the defense includes a printed interview conducted with California prior to his death from drowning in 1997. In the 1997 interview with Listener Magazine, the guitarist claims that some of the music from "Stairway to Heaven" was taken from his group's song.

(CNN) -- If this is an indication of what Roger Federer will do at Wimbledon, his opponents had better watch out. 

Federer recorded the second double bagel of his career when he defeated wildcard Mischa Zverev 6-0 6-0 on Friday to reach the semifinals of a Wimbledon warm-up in Halle, Germany. 

The only other time Federer didn't drop a game in a match was at the year-end championships in 2005 against clay-court specialist Gaston Gaudio. 

"You never go to court aiming for such a score," Federer, who turns 32 in August, told reporters. "I'm surprised to have managed it today." 

At Wimbledon, which begins on June 24, Federer will be bidding to advance to a first grand slam final since claiming a seventh title on the Wimbledon grass a year ago. 

He lost to Tomas Berdych in the U.S. Open quarterfinals last September, Andy Murray in January's Australian Open semifinals and Jo-Wilfried Tsonga in this month's French Open quarterfinals. 

Federer knows the chances of registering a second consecutive double bagel are slim. He meets local favorite and the man who beat him in last year's final in Halle, Tommy Haas, in the last four. 

"I expect a completely different opponent tomorrow," Federer said. 

Haas and Federer, good friends, played doubles together this week in Halle. 

"He is one of the greatest of all time, perhaps the greatest," said Haas. 

Haas, the 35-year-old third seed, rallied from a set down to oust Gael Monfils 6-7 (4) 6-3 6-3. 

But he was the only German winner on the day. Besides Zverev, sixth-seed Philipp Kohlschreiber and eighth-seed Florian Mayer were also sent packing.  What are the answers to this following set of questions: 1. What sport is being played?

Plutarch (; , "Ploútarkhos", ; c. AD 46 – AD 120), later named, upon becoming a Roman citizen, Lucius Mestrius Plutarchus, () was a Greek biographer and essayist, known primarily for his "Parallel Lives" and "Moralia". He is classified as a Middle Platonist. Plutarch's surviving works were written in Greek, but intended for both Greek and Roman readers. 

Plutarch was born to a prominent family in the small town of Chaeronea, about 80 km (50 miles) east of Delphi, in the Greek region of Boeotia. His family was wealthy. The name of Plutarch's father has not been preserved, but based on the common Greek custom of repeating a name in alternate generations, it was probably Nikarchus (). The name of Plutarch's grandfather was Lamprias, as he attested in "Moralia" and in his "Life of Antony". 

His brothers, Timon and Lamprias, are frequently mentioned in his essays and dialogues, which speak of Timon in particular in the most affectionate terms. Rualdus, in his 1624 work "Life of Plutarchus", recovered the name of Plutarch's wife, Timoxena, from internal evidence afforded by his writings. A letter is still extant, addressed by Plutarch to his wife, bidding her not to grieve too much at the death of their two-year-old daughter, who was named Timoxena after her mother. Interestingly, he hinted at a belief in reincarnation in that letter of consolation. What are the answers to this following set of questions: 1. where was Plutarch born?
2. how far from Delphi is that?
3. how many kilometers is that?
4. what year was he born?
5. was he from a wealthy family?
