I remember this well from the 60s - although 'The Girl From UNCLE' had a more powerful effect upon me in some ways. I loved the music in particular. I was slightly shocked to see the high price being asked for the Corgi toy on Ebay. I must have destroyed mine years ago. I tried watching it on tape last summer but either ruptured myself laughing or dozed off, so I can't remember whether the clothes were any cop.
What was that about the Ivy Shop having Man From UNCLE-style lettering, Jimmy?
