It's been 13 years since Tom Petty and the Heartbreakers headlined a show in the U.K., but the group returned to the other side of the pond in memorable fashion last night with the first of two nights at the Royal Albert Hall. To celebrate, Petty welcomed Steve Winwood to the stage, and the two rock icons breezed through renditions of two Winwood cuts: the Spencer Davis Group's "Gimme Some Lovin'," which you can check out above, and Blind Faith's "Can't Find My Way Home."
