This boogie-ing outake was included on the 2004 Sanctuary Records special deluxe edition of The Kinks Are the Village Green Preservation Society plus the 2018 50th anniversary reissue of the album.
The instrumental is titled after the underwear of the Kinks drummer, Mick Avory.
"I'm glad that's an instrumental," Avory told Rolling Stone. "God knows what the words would have been. I used to take my trousers off when I got drunk and I used to have these horrible underpants with either skull-and-crossbones on them or some inscription. Everyone knew I had silly underpants."
