"Michael Finnegan" (variant spellings include Michael Finnagen and Michael Vinnegan) is an unboundedly long song. The origin of the words and music is unknown, but the tune bears similarity to " Here We Go Round the Mulberry Bush". The earliest documented reference is The Hackney Scout Song Book (Stacy & Son Ltd, 1921). It also appears in The Oxford song book, vol.2, collected and arranged by Thomas Wood (Oxford University Press, 1927).
