The first ever Glastonbury festival or the Worthy Farm festival as it was known back in 1970 was supposed to have the Kinks as headliners – but they were a no show and at the last minute were replaced by a Marc Bolan and his new band Tyrannosaurus Rex.

It only cost £1 to attend in 1970 with 1,500 people attending – fast forward 50 years Michael Eavis and now his daughter Emily Eavis who runs the event has created one of the undisputed greatest music festival brands in the world.

With your £1 entrance fee in 1970 you even got a free bottle of milk (yes kids – milk came in glass bottles back then) and Ernie the fastest milkman in the west that year was a huge hit for Benny Hill.

This was the first merchandising deal undertaken by Glastonbury proving that the festival was ‘delivering’ more than just Sex, Drugs and Rock n Roll.

Dolly Parton’s saxophonist years later even played the Benny Hill theme tune to 100,000 people in what was one of the biggest artists crowds Glasto has ever seen – the audience lapped it up (no pun intended).

From a product sales point of view the power that Glastonbury can have, is huge. In 2005 Kate Moss wore Hunter Wellies which sent sales soaring for them that year.

The picture of Kate in her choice of footwear even made it into the fashion magazines.
