Complete with sing-alongs of popular tunes and a visit from Santa, this Philadelphia Orchestra-orchestrated event is a must-attend.

If a mass of young people dressed as Santa completely freaks you out, better sit out Saturday, Dec. 13's Running of the Santas. At 4 p.m. thousands of St. Nick look-alikes will run from McFadden's (461 N. 3rd St.) to the Electric Factory (421 N. 7th St.) where Edward Kowalczyk, Gypsy Wisdom, Scott's New Band, The Wayside Shakeup and DJ Crix will provide the sounds for the North Pole party.
