I saw them in Ipswich Gaumont, circa 1963. I saw them but didn't hear much of them as there was so much screaming and the amps weren't like they are now!
I did find out the exact date when I went around "the Beatles Experience" museum in Liverpool last year. Needless to say my aging neurones have already forgotten what date that was!
We actually went there at the request of our 20-year-old son, a budding world-beating lead singer and guitarist himself(he wishes!)-just to show the "generation effect" of the Beatles music.
Oh and I met my husband in the early 70s so we have 2 copies of several of their LPs: time to switch from Mudcat and get on to EBay!
