Rob Gronkowski, Paul McCartney, Bob Weir

Rob Gronkowski is taking a break from partying on yachts, and is instead partying with two Rock and Roll Hall of Famers, Paul McCartney and Bob Weir. 

Gronk joined The Beatles frontman and the Grateful Dead legend on stage at Fenway Park during a performance of "Helter Skelter." The Patriots' All-Pro tight end looked comfortable providing vocal support and playing some air-guitar.
