How could this thread forget the irrepressible Louise Gold! Who first came to note as a Muppeteer puppeteering the full-body TMS monster Big Mama (who also popped up briefly in The Ghost Of Faffner Hall). Big Mama was a big brown monster with rabbit-like ears. Although performed on TMS by various puppeteers at one time or another, she was most often, and most memorably, performed by Louise Gold. Who of course was her legendary puppeteer on the 1977 Royal Variety Performance.
(Strange to think that Louise is currently appearing in Chitty in the very same theatre.... )
