I've got it. Heard this track by Jon as a teenager in June 1967. Loved it. Never managed to get a copy on tape and haven't been able to track it down anywhere ever since. 40 years on, courtesy of the remarkable Oldies Project, I now have a good quality recording and will probably play it all evening non-stop!
This has been a sort of lifetime ambition and achieving it is a quite amazing feeling that's as difficult to describe as it may be for most of you to appreciate.
The only search results I could come up with were, in fact, links to a Radio London BigL chart that the Oldies Project people had published. I thought that was all it would be, but that was nice and enough to make me glad that it wasn't something I'd imagined! To then realise that the charts were played every Sunday, and that the 11 June 1967 chart would be played today and that I could record it, knowing that it would be played, was just wonderful. (Otherwise I could have found myself listening to the shows with the mouse hovering over the recording button for weeks, months on end, and still not getting it.)
So everything stopped at 11am today and even an earthquake wouldn't have budged me. I took a chance that the internet connection would hold up. It did. They repeat the show on Wednesday so there'd have been a couple more chances coming up but I'm so, so pleased to have got it first time, now safely filed away in My Music. I'll put a copy on-line shortly so you can hear what has driven me mad over all those years.
I feel absolutely brilliant.
