Speaking of the musicians: does anyone know any information about temporary week-only musicians Phyliss B. Susen (the harpist in the Key To Otherland opera; she also appears on camera in 1237), John Wilson (Celebrations), Joe Dallas (Josephene The Short-Neck Giraffe), Charles Gleddich (Fathers & Music) or Joseph Bishkoff (Sharing)? Does Betty remember them?
Interestingly, Joe Negri also performed with the group, at least in You & I Together (when Michael Moricz was at the piano). Also, we know what instruments Joe and Phyliss played, but what about the others? I'm guessing for Bishkoff, the violin (i seem to hear some string music playing during the kids playing in the yard segment in 1713)?
Also, something interesting i should point out about 1326-1330: in that week, during the outro music, there's some kind of alternation with the musicians. On 1326, 1327 and 1328, you can hear Bobby Rawsthorne playing with Costa and Taylor, but on 1329 and 1330, it's just Costa and Taylor. I think the 1974 and 1975 seasons both had probably the best jazzy outro music. It's fun to hear Costa get creative going through the trouble to play the whole outro by himself and on his albums, but i think it got better when the musicians were added, as it gave the music a more slick, cool jazz feel.
