Pay close attention to jazz musician Brian Newman’s gigs— you never know when his friend Lady Gaga will show up. Thursday night, she graced Newman’s performance at the Gramercy Park Hotel’s Rose Bar and ended up singing “Someone to Watch Over Me” for a small crowd. Trumpeter Newman is a longtime collaborator of Gaga’s, and she also popped up at his shows at the Oak Room at The Plaza hotel. He tweeted, “Thanks to the 1&only @ladygaga for coming out to @GPHhotel tonight.”
