@azacavagin17 they did practice often in the YMCA at Bedlington station. Your granda John was a couple of years older than me and he lived next door to us in Coquetdale Place.
I remember the bands first gigg and I think it was your granda (electrician?) who connected four coloured light bulbs to aa slab of wood and added an extension cable with an on-off switch. I sat under a table, covered by a cloth, and operated the switch = off and on to the beat/rythm of the song the band was playing. The band bought me my first under age pint of a Blank and Tan. I can't be sure of the venue of this first gigg that would have been 1964, or 65, but I thnk it might have been netherton Colliery or the Top End of Bedlington.
I know the band were riginally named the Statesmen but can't remember when they changed to the Olympics - (to me).
Just remembered your granda's son fitted my kitchen when we were living in cramlington. Think it would have been in the 1990's and the two of them, I think, were living in Millbank Road.
