I went to the Piccadilly (Tunes of Glory, Alec Guiness and Susana York) , the Waldorf (Some roman epic) close to the rink, Imperial, Moseley Rd, (The Girl With Green Hair, Rita Tushingham). The first technicolour I saw was Treasure Island, and it was set where I now live - but I can't remember where I saw it!
The place I went to most, because it was close and cheap for Saturday mornings was the ''Bug 'ut'', aka the Olympia on Ladypool Rd.
