As a said Bill a cud nivor spel propaley
There was a few local groups around at that time, The Avengers as you have already mentioned, The Dynacords and the Olympics to name just three.
I remember the Avengers and the Olympics used to practice at the YMCA at the station, I think Alan has mentioned that in previous posts.
I remember the Dynacords used to practice in the Wharton but I did not see them much, it was good for Bedlington to have so many groups.
Last time I was in Bedlington (a couple of months ago) I was talking to a friend of yours, Bill, Mr Mcgregor and hopefully will be having a pint with him again in September as we are coming up for the week.
