The classic line up at CBGBs famously went into reverse in terms of the band's record sales. Headliners Television had one album which just scraped the Billboard 100 then disappeared, and their sequel Adventure sold poorly. The Ramones had hits and solid album sales, but less than the band below them on the bill, Talking Heads.

They were called Blondie, one of the biggest selling bands in pop history.
