I suspect that by the late 1980s/early 1990s many Revival singers had almost empty forthcoming gigs diaries. As I recall the Revival was at a low ebb at that period. Both of my favourite trad. clubs, in both my home town and my adopted city (on opposite sides of the country), were long gone by then. The scene was not nearly as healthy as it had been in the 1960s/1970s. Perhaps Mr Bellamy's unhappiness ran deeper than that?
