'Riverdance'

You can Riverdance if you want to. You can leave your friends behind. 'Cause your friends don't dance, and if they don't dance, well, they're no friends of ours - or Michael Flatley's. That said, there are still tickets available for this weekend's "Riverdance" performances at the Providence Performing Arts Center. The PPAC website says this is a "farewell tour" for the Irish step-dancing show, but we'll believe it when we (don't) see it. 8 tonight, 2 and 8 p.m. tomorrow, and 1 and 6:30 p.m. Sunday. $38 to $65. Providence Performing Arts Center, 220 Weybosset St., Providence, 617-421-2787. ppacri.org
