PAUL MCCARTNEY performed in Boston on Sunday night, and the concert included an unexpected jam session featuring Paul, BOB WEIR from GRATEFUL DEAD, and ROB GRONKOWSKI from the New England Patriots.
It was the first time that Paul and Bob had shared a stage . . . and so it’s also the first time that Paul, Bob, and Gronk performed together, as hard as that may be to believe. (???)
Bob joined Paul for the encore . . . playing “Hi Hi Hi” by Wings and “Helter Skelter” by the Beatles. Gronk came up onstage to do some air-guitar during “Helter Skelter”.
