If my memory does not fail:

Cadbury fiddle (White Tiger),
fiddles (Fibula/Letty/Skipjack),
Banjo/Guitar/Mandolin (Leadfinger/Mooman/Eri[take your pick: c/k])),
Whistles (Peter/Liz/MudGuard [but only at beginners level]),
Squeezebox (Manitas),
Voices (Liz/Pat/Letty/...)
Shaky Egg (Letty)

Don't remember/know what John Giok or EriMaidin are playing

==> Skarpi, you should bring what is still missing: Church Organs ;-)
