Just a gentle muse....
Maybe the fact that 30 years later, (Yes, I'm another one!) The Global village has finally come to pass.
In the same way that virtually every UK town centre is identical..ie, MacDonalds, Clifton Cards, etc,etc...
It was probably inevitable, that with easy travel, multitudinous CD's etc, Music played in sessions would go the same way....Mind you, when you do discover a new gem, you tend to appreciate it more!
Off now to the water treatment plant at Beckton, to ponder on lifes rich and homogenous tapestry...!

Interesting though Ralphie
