I missed the first two days of secondary school in 1978 due to my attending the Reading Rock festival that year.
Saw, amongst others, The Jam (Legends), Status Quo, TRB, Patti Smith, and John Peel was the MC and swore like a trooper-a bit of a shock.
Handbags, if you go to the away pub, The Fernhurst, then make sure you try the Ewood Bakery first-best pies in Blackburn. (When he opens that is, usually too busy servicing his hareem of nubile pie sellers.)
