I think I saw them for the first time on the same Tour at York Barbican Andy. I didn’t note the date, the memory fades, it may have been prior to 2010.
Get Mrs FMF to buy you this triple album for Xmas, I recommend it. Lots of interesting sleeve notes from my fellow Lancastrain Ian Anderson in how he chose his favourite 50 tunes in 2018.
I know nothing about the music of Wishbone Ash, except its rock and was liked by long haired types who were into Yes, ELP, Led Zep etc. I saw the Moody Blues in 1973, performing Threshold of a Dream in its entirety. My favourite and most impressive concert I ever witnessed in Preston Guild Hall, despite the poor acoustics of that place. I knew some ex-university bods who also liked Wishone Ash. Not being particulary acedemic, I started work at 16 myself and starting around 1969 enjoyed the music from The Who, soul music, disco, reggae and later jazz funk and neo-jazz music. But somewhere along the way I came across Led Zep, Tull and Uriah Heap after listening to friends albums and I bought them myself. Many genres hihi!
