Chris Martin and Johnny Buckland help out their pal...

COLDPLAY‘s CHRIS MARTIN and JOHNNY BUCKLAND appear on Echo And The Bunnymen frontman IAN McCULLOCH’s new solo album .

The duo are repaying the compliment after McCulloch’s friendship helped COLDPLAY through he recording of their second album ‘A Rush Of Blood To The Head’ in Liverpool earlier this year.

The band have openly acknowledged the debt, and have even covered the [a][/a]classic ‘Lips Like Sugar’ at live shows this year.

Mac’s as-yet-untitled album, his first solo LP since 1992’s ‘Mysterio’, is expected to be released in March.

Martin sings backing vocals on two tracks, while actor John Simm, who plays in his own band Magic Alex, also features on the LP.
