I'd forgotten about them , great band . I remember a live album as well something about Wythenshawe comes to mind .
Had a white sleeve with 'slaughter & the dogs in red ' on a kind of sticker from what I remember .
Don't think this helps you mate actually - sorry - guess it's another question .
Any of these ring a bell - for either of our questions ?
I think that album is 'Live slaughter rabid dogs' belle vue manchester in 78 - it had the stickered writing in red on it. I tracked that down and have it on vinyl - alas its not the one I remember.
