I've been very familiar with the track "My Dark Hour" for a long time now. But what surprised me was I recently saw a mention that McCartney is also on "Celebration Song" on the same album. Only problem is listening to the track, I'm not sure I believe it. A google search shows the same claim about "Celebration Song" stated in many different places - but its not clear where this notion came from. My copy of the CD for the album "Brave New World" - has pretty spares notes... It mentions "Paul Ramone" on "My Dark Hour" but it doesn't say anything about any other tracks. Listening to "Celebration Song", I don't hear any obvious Paul McCartney singing or playing. The writing credits are for Steve Miller and Ben Sidran. One internet web site even mentioned a 3rd song McCartney supposedly played on ("Your Saving Grace") but that's not even the same Steve Miller album. Again, it doesn't really sound like Paul on that track either. Are any of these claims substantiated ? I see comments from Paul about the night "My Dark Hour" was recorded - but the story sounds like a jam session (which is how the track sounds).
