A grand piano used by Fleetwood Mac for crafting some of their biggest hits is set to be auctioned. Estimated to sell for $100,000 to $200,000, the black Hamilton grand piano was previously owned by Stevie Nicks before passing to Robbie Patton, who claims that Christine McVie composed iconic songs like ‘Songbird’ on it. After its initial use, it has also been played by Elton John and Freddie Mercury. The auction ends on December 6.
