Songwriting library assistants are hoping to turn their musical notes into banknotes to help victims of the Asian tsunami.

When Shaun Liddell, Peter Kidd and Steven Clayton, who all work for Durham County Council's flagship Clayport Library, discovered they all played different musical instruments, they decided to form a band - Infinite Monkey.

And now the trio have written and recorded their own composition, Growing Colder, and hope to sell the CD to raise money for the wave disaster appeal.

"I was playing one night and came up with the words and basic tune which together we developed,'' said Shaun.

"It was recorded at home on a 24-track recorder, then we mixed it at the White Wolf Recording studios in Derwentside where owner Ian Thompson gave us a deal, once again proving that if you show people a way in which they can do something, then they're only too happy to help."

A second song on the CD, Library Man, was written to mark the retirement of a colleague.

The CD is available from Clayport Library, Durham City and Durham's County Hall at Aykley Heads.
