A guitar owned by the former Pink Floyd musician David Gilmour has sold for a record breaking £3.13m to an American football billionaire who owns some of rock's most famous instruments.

Jim Irsay, who owns the Indianapolis Colts, purchased the 1969 Fender Stratocaster that featured on ‘Dark Side of the Moon’ and ‘The Wall’ in an auction in New York on June 20.

The sale of the heavily modified electric guitar, commonly known as “the black Strat”, broke the previous world record of £2.1m paid for a charity Stratocaster signed by 19 of the world's top rock guitarists, including Mr Gilmour, in 2004.

Mr Irsay, 60, also bought the vocalist's favourite guitar, the Martin 1069 D-35 acoustic, for over £789,400 during the David Gilmour Guitar Collection auction held at Christie’s.

Mr Gilmour’s entire guitar collection, which featured more than 120 instruments, raised nearly £17m for the musician’s charity, ClientEarth, which tackles climate change, famine and homelessness.

Mr Irsay, who is worth an estimated $2.7 billion, already boasts a collection which includes a 1963 Gretsch guitar once owned by John Lennon and the Yellow Cloud guitar played by Prince.
