I know Steve,
Anyway you are the sort of chap who likes facts; one morning I started watching Tiswas, Chris Tarrant came on wearing a ITTOD Tshirt (Paper Bag design) and said last week on the show John Bonham & Robert Plant asked a question about the band , and Chris chose the lucky winner from a piile of postcards.
Tiswas at that time was a locally networked show on a Saturday morning in the Midlands.
ATV the channel it was broadcast on may have been on strike.
As for a timeframe after Aug 11th and berfore Sept 10th the start of my school year.
Any light anyone can shed on this....
