Question: How much does the person Iron Man showed up at Grand Central Station with weigh? Passage:Doom hires various villains to find the bricks for him, starting with Abomination and Sandman, who hold Grand Central Station at ransom for a Cosmic Brick. Iron Man and Hulk show up at the station, with Spider-Man joining them later on, and together they manage to defeat the two villains, who are subsequently imprisoned in a nearby maximum security prison called the Raft, while Nick Fury leaves the Cosmic Brick in Mister Fantastic's care at the Baxter Building. Mister Fantastic and Captain America arrive at the building shortly after to examine the Cosmic Brick, but find it under attack by Doctor Octopus, who steals the brick and leaves his Octobots behind to keep the heroes busy. After destroying them, Mister Fantastic and Captain America chase after a fleeing Doctor Octopus across several rooftops, with their battle going through the Daily Bugle as well, where Peter Parker, Spider-Man's alter-ego, sees them and suits up as Spider-Man to lend a hand. The three heroes eventually battle Doctor Octopus in Times Square and manage to defeat him, but he tosses the brick to Green Goblin, who takes it to Oscorp. Fury sends Black Widow and Hawkeye to get it back, with Spider-Man joining them later on. They eventually confront Green Goblin in his office, but he opens a trapdoor that sends the heroes to Oscorp's underground lab, where they are forced to fight Venom and his symbiote-infected scientists. Although the heroes defeat Venom, the Goblin escapes with the brick via helicopter.

Question: Who were the members of the band that  recorded  "Bend Me, Shape Me" after they had reached the top ten with "Time Won't Let Me" in 1966? Passage:The group was formed in Cicero, Illinois, United States, as Gary & The Knight Lites. The founding members included Gary Loizzo (vocals and guitar), Charles Colbert, Jr. (bass guitar and vocals), Al Ciner (guitar and vocals), and Jim Michalak (drums). Early releases included- "I'm Glad She's Mine," "I Don't Need Your Help," "Will You Go Steady," "Take Me Back," among others. The group's greatest success as "The American Breed" was the single, "Bend Me, Shape Me", which reached number five on the U.S. Billboard Hot 100 chart in 1968. The song, written by Scott English and Larry Weiss, had previously been recorded by an all-female band known as the Shape and had been a hit on the UK Singles Chart for the British group Amen Corner. It had also been recorded by The Outsiders after they had reached the top ten with "Time Won't Let Me" in 1966. Contributing to the success of the American Breed's version of "Bend Me, Shape Me" was the excellent arrangement of the song by the band's record producer, Bill Traut, who added horns among other changes. The group also appeared on the 16 December 1967 episode of the television show American Bandstand, along with Pink Floyd.
