It's called "Hitsville USA": the little house on West Grand Boulevard in Detroit that Berry Gordy, Jr. bought as a home for the fledgling record company that grew up to become the legendary Motown.
These days, Hitsville is a museum dedicated to sharing the Motown experience with fans that come from around the world.
One such fan was in Detroit on a Sunday in July 2011. And before he performed for 37, 854 fans at Comerica Park, Sir Paul McCartney had one request: to visit Hitsville.
