One of the stylistic links between Bowie and the Stones is the use of acoustic guitar for rhythm guitar on out-and-out rockers, with the acoustic heard prominently at a song's beginning.  I don't have to name the instances, I'm sure.

But whatever happened to the rumor, which was well-heard at the time of the song's release, that it's Bowie playing the acoustic on "It's Only Rock 'n Roll"?  In 1974, that rumor seemed to have been issued to the press by the Stones camp.  Does anyone else remember this?  I doubt it's true, but it was definitely put out there with the album release hype.
