Michele Bachmann and Jimmy Fallon seemed oblivious to The Roots' choice of welcome song.

Updated at 4:41 p.m. PT

Jimmy Fallon's house band the Roots didn't have a warm welcome for Republican presidential contender Michele Bachmann when she appeared on the NBC show early Tuesday.

As Bachmann strode on to the stage for an appearance on Fallon's "Late Night" early Tuesday, the show's band played a snippet of a Fishbone song called "Lyin' Ass Bitch."

(Msnbc.com is a joint venture of Microsoft and NBC Universal.)

The song begins with a distinctive "la la la la la la la la la" refrain — the only words audible before Bachmann, smiling and waving to the audience, sat down.

The song itself, about a relationship gone wrong, isn't political. Among its cleanest lyrics: "She always says she needs you, but you know she really don't care."

Bachmann's campaign had no immediate comment.

Fallon joked on Twitter that Roots bandleader Ahmir "Questlove" Thompson was grounded. The show itself didn't have any comment.

"Aight late night walkon song devotees: you love it when we snark: this next one takes the cake. ask around cause i aint tweeting title,"  tweeted Questlove.

Fallon took to his Twitter account on Tuesday afternoon to issue an apology. "I'm honored that @michelebachmann was on our show yesterday and I'm so sorry about the intro mess. I really hope she comes back," he tweeted. "Actually, it was a really fun interview. She helped me with my Minnesota accent. (I still sound Irish.)

The Roots frequently make sly, often obscure, song choices as Fallon's guests are introduced.

When Fox Business Network's Lou Dobbs came out, they played part of Genesis' "Illegal Alien," a reference to Dobbs' frequent commentaries on the topic. Current TV host Keith Olbermann, formerly of MSNBC, heard part of Klymaxx's "I Miss You." Kathie Lee Gifford was saluted with UB40's "Red Red Wine," a reference to the drink she often shares on-air with "Today" co-host Hoda Kotb.
