See David Cassidy for free

David Cassidy, touting his new show on ABC Family called Ruby & the Rockits (he plays a former teen idol), will  concertize at 7 p.m. Friday (8/14) at TD Bank Amphitheatre, 2400 Byberry Rd., Bensalem.

Ross Brittain of WOGL will host.

With CBS's involvement, you'd think that Cassidy's onetime TV costar, WYSP morning man Danny Bonaduce, would be a natural to show up and maybe knock out a chorus of "I Think I Love You." But Cassidy and Bonaduce aren't the best of buddies. And Bonaduce didn't sing on The Partridge Family.

Bonaduce also will be marking his 50th birthday that night at Bally's in Atlantic City.
