Ex-Beatle Paul McCartney headlined “Saturday Night Live” as the musical act, and sang what may be an unprecedented four songs during the show. He also appeared in some skits. But did he lip-sync his John Lennon tribute?

The alleged lip-syncing occured during the medley of “A Day in the Life” and “Give Peace a Chance” in what was a touching tribute to slain Beatle John Lennon.

He was murdered 30 years ago this past week by a deranged fan.

Two other songs, “Band on the Run,” and “Jet,” both from McCartney’s Wings era, seemed to be the real deal.

“Jet” suffered, however, from a poor vocal mix and musicians whose back-up “woo-woo”s sounded like off-key hound-dogs,” according to Entertainment Weekly.

McCartney closed the show with a quick version of “Get Back.”

“Band on the Run” gets the highest marks of Paul’s quartet of tunes.

Roger Friedman, of Showbiz 411, called McCartney’s performance “refreshingly real.”

“McCartney and his band sang and played LIVE tonight. You kids may not know what that’s like. There was no lip-synching, or track, or ornamentation,” he writes.

McCartney is currently making the rounds to promote a new boxed set of “Band on the Run, which has been remastered with extras.

It’s also his first appearance since the Beatles were finally released as digital tracks on iTunes. So Paul’s appearance was likely also designed, in part, to stoke sales there.

McCartney will continue his run in New York City with a concert at the famed Apollo Theater Monday night (Dec. 13), hosted by Sirius XM Satellite Radio.
