The 1877 Steinway grand piano used by Motown greats during the 1960s has been completely restored thanks to Paul McCartney, and it's back home in Detroit after extensive work by Steinway Piano technicians.

The piano was delivered to the "Hitsville, U.S.A," building this week and workers set it up in a former recording studio in the Motown Historical Museum.

Paul McCartney, a longtime fan of the Motown sound who played and recorded several of the label's songs during the Beatles' early days, told museum officials after a 2011 concert at Commerica Park and a visit to "Hitsville" that he wanted to help with the piano's refurbishment after learning the historic instrument no longer could be played.
