Capone never sang to the feds, but his stint in Alcatraz turned him into a songwriter.
It turns out he penned a traditional Italian love song he called "Madonna Mia," but it has never been performed.
The song is soon to be released on CD. An inscribed copy of the music is now up for a cool $65,000, the Associated Press noted.
"Madonna Mia," by the way, is also a poem by Oscar Wilde, who spent some time in jail himself, although for entirely different reasons. Not sure if Capone was trying to tell us something there.
