Mellotronists

I found a used CD copy of Aussie band Sebastian Hardie's 
WINDCHASE(Musea),listened to it today, and one of the songs appears to 
be using the(gasp!) TED TAYLOR CHOIR! It's certainly not any usual 
choir sound I've heard(unless they recorded their own).It sounds like 
TT choir to me as I briefly had it on a rack in the 70s(by a mistake 
of Dallas Arbiter).Yechhh
