The song that first made the Bee Gees a “disco” band was “You Should Be Dancing,” hitting #1 on the Billboard Hot 100 in 1976. The song is also part of the soundtrack from “Saturday Night Fever.” The 45, released by RSO Records, is not a big collectible at $5.00 but it was also released to radio as a 12-inch single. A copy is worth up to $125.00 today. Both versions are shown here.
