In 1969, there were two massive free concerts in Hyde Park, one featuring the Rolling Stones, which Mick Jagger dedicated to Brian Jones following his tragic drowning, and the other the short-lived supergroup Blind Faith with former Cream members Ginger Baker and Eric Clapton, joined by Spencer Davis's Stevie Winwood and bassist/ violinist Rick Grech.

In the latter, a highlight for me was Eric's spine-tingling wah-wah effects in Presence Of The Lord.

They were preceded by the Edgar Broughton Band, who had a few hundred thousand people chanting "Out Demons Out" - a possible allusion to governments rather than the other forces of evil, just as easily applicable today.

But Normstock - a pun on Woodstock, also in 1969 - certainly isn't applicable.

In the vernacular of my youth, it was "a really heavy trip, man".

On the day, I took my three-year-old son to Thorpe Park with no queues and no crushing and had some proper fun.
