Anyway, duly tempted I walked out with Tull's Heavy Horses, Yes's Drama and Tormato, and Selling England By the Pound from the classic Genesis line-up. Of the four I'm familiar only with the Genesis, which I had on vinyl in the early seventies, so it was interesting exposing myself to material that I should know, have heard plenty about second hand, but have never in fact listened to.
The one with which I am familiar inevitably brought back memories of a time when I considered Messers Gabriel, Rutherford, Banks, Collins & Hackett as quite the coolest dudes on the planet - except nobody said dudes then. And then trawling the wilds of youtube I discovered this video of them doing what I think is the best track off the album live - which I think proves the point that they were (extremely cool) for any reader not around at the time. Click on Dancing With The Moonlit Night and enjoy a bit of a dance, do.
