Pink Floyd’s greatest hits, viewed from the audience.

1. 14 HOUR TECHNICOLOR DREAM, ALEXANDRA PALACE, LONDON, APRIL 1967

Where the first tranche of Floyd fans felt they’d sold out, moving from the confines of All Saints Hall in Powis Gardens and the UFO in Tottenham Court Road to be part of the multi-artist happening in Muswell Hill. Captured on film by Peter Whitehead as part of Tonite, Let’s All Make Love In London, Floyd appeared at the end of the show, as the Sunday sun rose across the capital, and with it, their role as underground house band of choice was secure.

2. GAMES FOR MAY, QUEEN ELIZABETH HALL, LONDON, MAY 1967

Probably the group’s most famous early concert, Games For May was immortalised in song by Syd Barrett on the Floyd’s first Top 10 single, See Emily Play. Described as a “Space age relaxation for the climax of spring – electronic composition, colour and image projection, girls, and the Pink Floyd,” frankly, what was there not to like? Playing more or less what was to become The Piper At The Gates Of Dawn, and premièring Emily, someone dressed as an admiral gave out daffodils to the audience while a bubble machine stained the seats, allegedly resulting in a lifelong ban at the venue for the group.
