One of their first releases was this single, 'Slaughter on 10th avenue'. What makes this single interesting for me is the B-side: it's a version of the Marty Wilde composition 'Polaris', which he created for a group called The Boys - which was a pseudonym for the Wildcats. And the Wildcats, of course, were the band who supported Marty, much like the Shadows did for Cliff Richard. I haven't found a copy of The Boys' version yet, but at least I have this cover version now.
