Following the various comments on the guestbook, I can confirm that the Collectors Club will draw to an exciting, honourable close at Club50. Club 46 The Marquee 1972, (one of the best sounding shows of the RF/Boz/Ian/Mel line-up) will be the last audio-only release. The last four Collectors Club releases will be DVDs (possibly with accompanying CDs), of which the first of which, Club47, will be a DVDA with footage of two shows in Buenos Aires in 1994.
So the reluctant completists are nearly there.
