I saw Frank Zappa & The Mothers of Invention 4 times,, always in NYC. That was at two concerts at the Palladium and two at the Felt Forum in Madison Square Garden and always on the night before Halloween. He and the Mothers of Invention were absolutely1970s fantastic. His songs usually told a story, for example Mudshark (the complete medley including Happy Together).
Turn up the volume and enjoy. By the way, this song is not for snowflakes of any ilk. If you are easily offended by weird raunchy sexual innuendo descriptive language, listen to it at the peril of you melting down. I readily admit, this is one of my favorite Zappa songs.
All the best,
Glenn B
