I had sounds like Bricks broken bottles, Skip Jackson, Jack Montgomery around 1969/1970 but only played them at home as they weren't fast enough for the scene then.
Imagine my surprise when I started going out again and heard them being 'played out'. I was also told by the person who bought my collection remnants around 1987 that they were 6 copies of the Constellations - I don't know about you - in the collection ( again wrong tempo at the time)
Hindsight is a wonderful thing!!
