Hi Gilly its Jegger. I remember the 76 club very well and was about 1976 when first went.You went down the little dark entry opposite Bargates then you went through a small door, small bar on the right set back. the room was small with booths down one the side small wooden dance floor with steps to other side,the DJ box and i mean box was next to the dance floor.had many a good night,as you said not dedicated all to soul music but do remember hearing most of the northern sounds of the time and remember a few DJ's of the time being there and if memory serves me right which is debatable these days Spiv was a resident DJ.
let me know when the book is ready.
cheers
Dave
