At a concert this summer in Clifton Park, New York, musician Matt Nathanson invited Andrew McMahon onstage to perform Tom Petty’s American Girl together. Before the song, Matt started to strike a few chords to AC/DC’s classic rock song Shook Me All Night Long. That was all the crowd needed to start singing. The band was in shock as the crowd took over the concert and sang the entire song.
