Todd Rundgren's Utopia

I just listened to the album “Deface The Music” last night. I understand that they were attempting to sound like The Beatles, and for the most part I think it’s pretty good.

My question for any Utopia experts out there: there’s a song on there called “Smiles” (or something like that). Is there any way that that’s NOT Paul McCartney singing this song? I mean, the other songs on the album SOUND “Beatle-esque,” sure. But that particular song sounds EXACTLY like McCartney. The other “Paul” songs on the album don’t sound that much like the real thing.

Anyone know the Straight Dope on this tune?

Thanks.
