my first twickers--the one i stayed at a rented room--was spent trainspotting on Wimbledon station platform--for hours, while mum attended the assembly. This lasted each day till it got dark--and mum got off a train and collected me--i was about 12 years old !!! ive no recollection of the assembly itself.
the next 2--and those at murrayfield--was spent with my mates--it was a holiday. I never sat and listened to any talks.
Slow forward a few years--newly married and attended rain soaked Wembley old stadium--actually sat in the rain bored stiff and not listening. Utter waste of time..and i'm proud to say it was the last big ARSEmbly i ever went to--about 1970 ?
