Don't know of any plans for reissues - would be interested to hear from anyone who does.
I read that RR's career began to tail off with the advent of John Surman as the number one British player so I guess he became unfashionable in some circles. But to me his improvisations were almost always very good and sometimes superlative. Having listened to all I can, including recordings of broadcast sessions at the British Library Sound Archive (an on-going program - see more additons to discography in due course) of which copies are not available, and tried to track his development, it seems that a big turning point for him was his rubbing shoulders with Mulligan in Paris in, I think, 1959. After this his sound changed, became more robust. On earlier recordings he has a lighter but still very attractive sound, but some of the BLSA sessions I've heard his sound was virile indeed. The latest session I heard, one of the tunes bordered on "free" ("Part Two" - 1985), which came as a bit of a surprise to me.
Greg Dyke, of the BBC, announced fairly recently that he would like to see the BBC archives made available on-line to anyone, free of charge I think. I don't see this happening anytime soon but am living in hope. The recordings might become available after fifty years but I doubt I'll be around to reap the benefit.
