Early personnel changes..

The early personnel changes in Rainbow are a little bit complicated. I hope I have the correct info here:

1972
David Cook
Weird scary looking Bungle voiced by John Leeson
Zippy voiced by Peter Hawkins - No George yet
Telltale Band (Hugh Portnow, Ted Richards & Tim Thomas)
Sunshine and Moonie - Sunshine voiced by Peter Hawkins (who voiced Moonie?)

Season 2 - Early 1973
David Cook
More familiar plump faced Bungle but still voiced by John Leeson
Zippy now voiced by Roy Skelton
George is introduced - voiced by Roy Skelton
Zippy has other friends but none stay as permanent characters (was one called "Freddie the Fox"?)
Telltale Band (Hugh Portnow, Ted Richards & Tim Thomas) still there
Sunshine and Moonie - (Sunshine voiced by Roy Skelton or still Peter Hawkins?)

Season 2 - Late 1973
Geoffrey Hayes
Bungle now voiced by Stanley Bates
Zippy and George voiced by Roy Skelton
Julian Littman, Karl Johnson and Charmian Dore - the singers only for one season (no more Telltale, although the theme sung by them continues)
Sunshine and Moonie disappear when Geoffrey takes over

1974
Same personnel except Jane Tucker, Rod Burton and Matthew Corbett take over as singers

1978
Same personnel except Roger Walker replaces Matthew Corbett

1980
Same personnel except Freddy Marks replaces Roger Walker

In the late 80's somebody replaced Stanley Bates as Bungle but I don't know his name.
