Muffin Man is a song recorded live by Frank Zappa and The Mothers. It appears on his 1975 mostly live album Bongo Fury made with Captain Beefheart (Don Van Vliet). The song begins with studio-recorded spoken word lyrics delivered by Zappa and is followed by the chorus. The song was inspired by the traditional nursery rhyme, The Muffin Man. The song closes the album, as well as the compilation Strictly Commercial, and was also used as a finale in concerts for many years afterwards. The song's tone was compared to Jimi Hendrix's style. An alternative live version of "Muffin Man" appears on disc one (track 22) of the compilation You Can't Do That on Stage Anymore, Vol. 6. This song also appears on the 2009 album released by the Zappa Family Trust Philly '76, the 2002 album FZ:OZ and the 2003 album Halloween.
Frank Zappa's son, Dweezil, along with his Zappa Plays Zappa (ZPZ) band, have featured "Muffin Man" on many concert tours. In 2010, they offered video footage of Frank Zappa playing "Muffin Man," along with isolated Frank Zappa guitar parts, so Dweezil and ZPZ accompanied live Frank Zappa and his extended guitar solo.
