This post from Paul Holmes on the the Old Clubland acts Facebook page is all that I know about this group.

“I said I would post this for my old friend & guitarists Pat the strat in the early 60s his band the Decoys from Nottingham made this single they had that look & sound of the Beatles & Shadows & did the clubs & dance halls throughout the uk.”

The single he refers to is referenced on Discogs
