Zac Brown Band wrapped up their third show at Boston’s Fenway Park last night, the first band to ever play a three-night run in the history of the famed ballpark. Towards the end of their set, the group welcomed out Aerosmith frontman Steven Tyler for a pair of his own tunes—“Sweet Emotion” and “Walk This Way.”

While “Sweet Emotion” is a common cover for the band, the Aerosmith classic “Walk This Way” made its ZBB debut with Tyler handling lead vocals. Another rare cover in the show came in the form of Temple of the Dog’s “Hunger Strike.” ZBB has only covered the Pearl Jam/Chris Cornell supergroup’s hit three times.
