"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.
