The Tom Petty and Steve Winwood tour has been going for a little over a month, but it wasn’t until Monday that the two came together on stage.

Petty brought Winwood out in Philadelphia for versions of Blind Faith‘s “Can’t Find My Way Home” and from Winwood’s days in the Spencer David Group, “Gimme Some Lovin’.” However, with Heartbreakers‘ keyboardist Benmont Tench‘s Hammond B3 facing the drums, Winwood sang the song with his back to the audience.

Next stop on the tour is Raleigh, North Carolina on Thursday.
