Rust Never Sleeps is the tenth album by Canadian American singer-songwriter Neil Young and his third with American band Crazy Horse. It was released on June 22, 1979, by Reprise Records and features both studio and live tracks. Most of the album was recorded live, then overdubbed in the studio, while others originated in the studio. Young used the phrase "rust never sleeps" as a concept for his tour with Crazy Horse to avoid artistic complacency and try more progressive, theatrical approaches to performing live.

"My My, Hey Hey " is a song by Canadian musician Neil Young. An acoustic song, it was recorded live in early 1978 at the Boarding House in San Francisco, California. Combined with its hard rock counterpart "Hey Hey, My My ", it bookends Young's 1979 album Rust Never Sleeps. Inspired by electropunk group Devo, the rise of punk and what Young viewed as his own growing irrelevance, the song significantly revitalized Young's career.
