Piano used in Beatles, Pink Floyd songs up for auction

The upright wooden Challen Piano once played in Beatles' favorites such as the Paperback Writer' and Tomorrow Never Knows, is being auctioned off by the Abbey Roads Studio later this month.

The Challen is expected to go for as much as $239,000 -- quite a return on investment considering that it was originally bought for just under $400. Between 1964 and 1980, the piano was famously used by the Beatles and reportedly by Pink Floyd when it recorded its Dark Side of the Moon album. Auctioneer Bonhams says that the piano bears plenty of cigarette burns and coffee stains from its years of use. But no worries, the rustic appeal ups the value of the piano since it serves as a reminder of its incorporation in such legendary tracks.
