Was Whipping Post the Freebird of its day?
From
Whipping Post (song) - Wikipedia
In a 1974 concert in Helsinki, Finland, an audience member repeatedly disrupted a
Frank Zappa performance by shouting a request for "Whipping Post." Zappa responded by playing a version of his song "
Montana",
[23] where he altered the lyrics with references to whipping posts.
[22] (This incident was eventually captured on his
You Can't Do That on Stage Anymore, Vol. 2 live album, released in 1988.) In 1981, Zappa's band learned "Whipping Post" and added it to their repertoire, since the band's new singer and keyboard player
Bobby Martin knew the song and sang the lead vocals on it.
