Studio and live versions of "Boom Boom (Out Go The Lights)" were recorded by Pat Travers, both uptempo with some fine axework, and, one might think, this was a happy sort of song. In fact it has a somewhat dark origin. Written by harmonica player Stan Lewis it was recorded by another harmonica player, Little Walter on Chess Records. Marion Walter Jacobs (1930-68) was inducted into the Rock & Roll Hall Of Fame in 2008.

Listening to the song with a bit of nous reveals that it is actually about a taboo subject - spousal abuse; the boom is the punch, and out go the young lady's lights.
