Dan Gross: So you think you can sing? Bensalem's Christina Perri can

BENSALEM native Christina Perri's "Jar of Hearts" has blown up on iTunes after the Archbishop Ryan grad performed the mournful ballad on the Fox hit "So You Think You Can Dance."

We reported a few weeks back that Perri's song would be heard during a dance performance. It was so well received by fans that she was asked back to sing live.

Perri, who turns 24 soon, moved out to Los Angeles on her 21st birthday, says mother, Mary, who owns Perri's Barber & Hairsyling (2755 Hulmeville) in Bensalem with her husband Dante.

Screech to ref wrestling match

If you thought a Big Bang Wrestling match between Tiger Woods mistress Devon James and Susan Finkelstein, whose claim to fame was allegedly offering Bensalem Police sex for World Series tickets, couldn't get sillier, you were wrong.

Screech will referee the bout.

Dustin Diamond, who played Screech on "Saved by the Bell," refs Thursday's James/Finkelstein bout at Pennant East (Crescent & Kings), in Bellmawr, N.J., and will also appear at 7:30 Wednesday night at a free press conference/party at Cavanaugh's River Deck (417 N. Columbus).

Who put this together? You guessed it: Damon Feldman.

Tix are $20 at the door Thursday for the 8:30 p.m. absurdity.
