Sonny and Cher's first album, "Look at Us" (1965), released for the Atco Records division of Atlantic Records, spent eight weeks at number two on the "Billboard" 200, behind the Beatles' "Help!". Their material became popular, and the duo successfully competed with the dominant British Invasion and Motown sounds of the era. Author Joseph Murrells described Sonny and Cher as "part of the leading exponents of the rock-folk-message type of song, a hybrid combining the best and instrumentation of rock music with folk lyric and often lyrics of protest." Sonny and Cher charted ten "Billboard" top 40 singles between 1965 and 1972, including five top-ten singles: "I Got You Babe", "Baby Don't Go", "The Beat Goes On", "All I Ever Need Is You", and "A Cowboy's Work Is Never Done". At one point, they had five songs in the top 50 at the same time, a feat equaled only by the Beatles and Elvis Presley. By the end of 1967, they had sold 40 million records worldwide and had become, according to "Time" magazine's Ginia Bellafante, rock's "it" couple.
