What a good message, enjoyed it immensely. I take many of your points and can't disagree, they certainly were a one-off band. But people all mature. Certainly, all artists do. They have to develop to breathe, to survive. Try later works such as Poetic Justice", "The Quality Of Mercy" and "Stranger Comes To Town". You will find many of the old SH quirks in there as well as songwriting from the top drawer, by a mature, experienced and ever-alert man. He sees the real world, even though he often says he doesn't actually mix much - "Journey's End", if you have teenage/grown up children, will break your heart. "A Friend For Life", "This Old Man" - so many touching tributes from Harley's pen to the vagaries of modern life and the world of the Outsider, as he surely still is, like all great artists.
The two first albums in one concert will indeed be an occasion to savour - I'll pay top-dollar for tickets, and I hope it's in the Royal Festival Hall rather than the much smaller, odd-shaped Cadogan Hall.
And as for his asking the original members to jopin him that night - wjhat an amazing idea, one nobody else has yet offered on this Forum. Let's hope the bridges have been mended, and that the guys would be up for it! Would be sensational news for the Press/Media to help promote the show with!! Steve - are you there? Can it be done??
