Paul McCartney has made a previously unreleased Wings song available to his fans as a free download.

The track, "Love My Baby," features McCartney singing along with a celeste and was recorded for the 1974 Wings documentary film One Hand Clapping, in which McCartney and his band play songs from the 1973 album Band on The Run.

The track is available on McCartney's website for fans who add their name to the mailing list.

Last fall, when the song first surfaced online, McCartney said of the track, "It was made by a friend of mine, David Litchfield."

"We decided that he would shoot a very simple piece, on video. We would just go into Abbey Road and play basically what we had rehearsed. So we went in there and it was very simply filmed, absolute basic stuff, and I think its charm now is that there's no pretense. It is what it is."
