The Yellow Shark, An Appreciation. Merry Zappadan.
So many Zappa titles remind me of this (embedding disabled, worth the click).
From Barry Miles’ Zappa: A Biography:
England also inspired the title of ‘A Pound For a Brown On The Bus’, an attractive tune originally written for a string quartet in a music competition that William Ballard, Frank’s high-school music teacher suggested he enter. When the Mothers flew in from Amsterdam to play the Royal Festival Hall, they were provided with a coach to take them to the Winton Hotel. The bus had very large windows and during the trip Jimmy Carl Black made a wager with Bunk Gardner: ‘I’ll bet you a pound you won’t Brown Out on this here bus.’ Gardner had his trousers down and his cheeks spread across the window before anybody knew what was happening.
If there is a Zappa piece that sounds like Christmas, it is this performance of “Pound For a Brown.”
