The Revolution will not be televised

There's an irony to these words in the year of the Arab Spring and the youtube revolutions.
I was really saddened to hear that Gil Scott-Heron had died at the unfeasibly young age of 62. He was only 20 when he wrote and recorded The Revolution will not be televised.
I have a good memory and can usually recall details of concerts I've been to - in fact it's the intensity of the memories and the recall of detail that inspired me to start this blog. With Gil Scott-Heron I'm not so sure. I believe I saw him at the International in Manchester in the early 80s. In a way it's his death that has made me doubt myself - I can't believe I saw such an amazing performer at that time and in such a venue.
There's a website that lists the acts booked there, but it starts in early 1985 and I know it must have been before then. I came back from working in Morocco in 1981, and was pregnant with my first child in 1984, so it was somewhere in those years between.
Around the same time I saw Curtis Mayfield and Bo Diddley at the same venue ( different nights! - that would be too much!)
For those concerts I can recall where I stood, who I was with, who I bumped into at the bar, but seeing Gil Scott-Heron has a vaguer, dreamier quality to it. I can't blame drink or drugs - maybe it was a more intense experience. I was drawn to his name as well as his music - like a little poem in itself..
If someone told me I'd imagined it all, and that he didn't play Manchester during those years, I'd accept that I'm under a delusion, but I'd also be really impressed by my ability to conjure up a Gil Scott-Heron performance in my dreams.
