Whatever happened to forgotten bands such as Sloan Square East, Clocks and Clouds Funky Monorail, Wicked Rich and Ilkley band Summon Bonum?

Bradford Rock historian Gary Cavanagh wants to know. More than that, he wants to hear their recordings – Hands Reach Out, The Fear, and Song for Gary.

Mr Cavanagh is compiling a sequel to the book he did with Matt Webster last year, Noise of the Valleys – a compendium of Bradford bands, bits of local history and characters such as Seething Wells and Wild Willi Beckett, accompanied by CDs of their music.

That £19.99 volume, which covered the period 1967 to 1987, has sold about 600 copies to date and, says Mr Cavanagh, has turned up in Australia, Denmark, Canada, the United States and Vietnam.

Volume II of Noise of the Valleys has an updated preface, covering 1988 to 1998 and is due out next summer, he hopes.
