Here’s a good one off the top of my head. Roxy Music’s 2HB, Ladytron, and Bitter-sweet were all on the soundtrack to a movie in the 90s (Velvet Goldmine). They were all recorded by the Venus in Furs, which was Johnny Greenwood and Thom Yorke from Radiohead with the bassist from… Suede (I think, probably wrong), as well as Andy MacKay from Roxy Music. Definitely still covers imo. Even with one of the original Roxy guys in the band. If Bryan Ferry and / or Brian Eno were part of the band that might make it harder to definitively say they were covers, especially Ferry. His voice made Roxy imo. Thom did incredible with it though.
