When you're a headliner, you're awarded certain privileges. When you're playing your hometown, you probably even get more favorable treatment. And if you're a band as big as Aerosmith and your opening act is the equally impressive Cheap Trick, you've got to take advantage of the situation to guest on a classic song.

That's exactly what happened Thursday night (July 19) at Boston's TD Garden when Cheap Trick's Rick Nielsen brought out Aerosmith's Brad Whitford to the stage to join them on the classic track, 'Ain't That a Shame.' While Nielsen's riffs in the song are quite signature, Whitford was allowed to slip in a breakdown here and there and add his own take to it. As seen in the fan-shot video below, Whitford is definitely enjoying the experience.

The 'Global Warming' tour featuring Aerosmith and Cheap Trick will continue through Aug. 12 in Bristow, Va.
