Fans in Boston were treated to the talents of Paul McCartney on Sunday night, as the legendary ex-Beatle brought his "One On One" tour to Fenway Park for a night of music and merriment.
New England Patriots tight end Rob Gronkowski was among the many in attendance to watch the 74-year-old rocker -- after all, the Summer of Gronk is still very much in full effect. But Gronk's concert experience was slightly different than that of the average fan in attendance.
Friendly reminder: you may be cool, but you'll never be Rob Gronkowski playing air guitar while on stage with Sir Paul McCartney and Bob Weir cool.
