The act consists of Labour’s Ian Cawsey on bass and lead vocals and Kevin Brennan doing guitar and vocals, Tory Greg Knight on drums and SNP’s Pete Wishart on keyboards.

Frontman Ian Cawsey said: "We are very excited at the launch of our first single and to be supporting the development of legal downloading."

“At a time when many musicians have become politicians this is the backlash. Politicians masquerading as musicians; you have been warned!"

Peter Jamieson, chairman of the UK record companies trade association the BPI said: "This is an opportunity to buy a piece of history and raise money for charity as well. Never let it be said that MPs are out of touch. Just like the record industry itself MP4 are embracing the download revolution.”
