A Lindner upright piano Abba used to write some of their best loved songs has sold for £35,000 ($53,068) at Bonhams.
The lot led an auction of entertainment memorabilia in London earlier today.
The band holed themselves up on the tiny Swedish island of Viggso during the summer of 1972 and set to work writing.
Bonhams explains: "The cottage owned by Agnetha Fältskog and Björn Ulvaeus was established as the base for ABBA's creative writing sessions from 1972.
"It has a small holding which was just large enough for the piano in this lot and two chairs to fit in.
"Benny Andersson recalled carrying the piano up to the house in the wintertime and carrying it back down to the small writing hut when spring arrived so that the group could play and compose all summer."
Andersson remembers it as "not one of the best pianos I have played on but it sure did the work well to compose some good songs on."
Since that time, the piano has passed through the hands of a number of owners. For many years it formed the centrepiece of the Abba Museum in Stockholm.
