The 1973 smash song “Piano Man” made Billy Joel famous. On Thursday night, he called it quits on his ten-year run at Madison Square Garden in New York. On the 104th show of his monthly residency and his 150th show at the renowned Midtown Manhattan arena, the 75-year-old singer-songwriter gave his farewell performance. Almost 20,000 admirers cheered as the Grammy Award-winning singer announced, “This is our last night of the residency that we’ve been doing here.”
