Led Zeppelin's long unreleased "Sunshine Woman" is now available for official consumption. The band has released the only take of this lost track, previously available on various bootlegs, in advance of its inclusion on the upcoming The Complete BBC Sessions.

Jimmy Page, who oversaw this expanded reissue of 1997's double-platinum BBC Sessions, has been frank about the fidelity issues surrounding "Sunshine Woman." "There's no point pretending it wasn't recorded off the radio," he told Mojo (via the Guardian). Still, new Zeppelin is new Zeppelin, right?

You can listen to the song below.

The Complete BBC Sessions, which collects Zeppelin live recordings made by BBC radio between 1969-71, is due Sept. 16. This is one of four unearthed songs – also including different takes on “Dazed and Confused,” “I Can’t Quit You Baby” and “You Shook Me” – from a 1969 appearance that was long thought to have been lost. In all, the project includes eight previously unissued songs – though "Sunshine Woman," which never appeared on any studio recording, is the only one to gain a sort of holy-grail status.

Page said the track was "basically made up on the spot" during Alexis Korner's World Service Show in March 1969. "It was pretty brave, bearing in mind the circumstances," he added. "We played it as if we were in rehearsals, starting it around the riff and then working it out. It shows that we were evolving pretty quickly.”

The set's other unheard items include two versions of both “Communication Breakdown” and “What Is and What Should Never Be,” recorded two years apart.
