Exclusive | Bill Murray crashes piano players set at NYC celeb hotspot Bemelmans to sing this 70s hit

Who you gonna call but Bill Murray to crash a set?The “Ghostbusters” actor, known for interrupting events such as a White House press briefing, bachelor party, and even a couple’s engagement photoshoot, was at it again on Wednesday when he crashed a piano player’s concert.Murray, 74, was an audience member at Bemelmans Bar, inside the famed Carlyle Hotel on the Upper East Side, listening to the tunes of singing jazz pianist Robert Mosci when he felt the need to join in.“I didn’t know he was coming.The way it unfolded was quickly and funny,” the accosted pianist, Robert Mosci, told The Post.“He came over to me and he said, ‘Hey, do you know the song ‘Brandy?'”Mosci confessed he never played it before, but Murray remained undeterred.
