Pink Floyd: A Technicolor Dream, 9.00pm, Sky Arts
Streaming on NOW
I’ve always felt that early Pink Floyd were far more interesting (and groundbreaking) in their early, Syd Barrett days. They became terribly dull in later years.
As evidence, here’s a documentary about a legendary 1967 concert at Alexandra Palace in London where revelers including John Lennon dropped acid and listened to Marc Bolan, the Pretty Things and Pink Floyd.
I think it’s fair to say they were very trippy times.
Followed at 11pm by Have You Got It Yet? The Story of Syd Barrett and Pink Floyd.
The life of the band's original frontman, charting his creative and destructive impulses, his breakdown and exit from the group and his subsequent life.
Featuring interviews with Syd's friends, lovers, family and bandmates Roger Waters, David Gilmour and Nick Mason.

Wonderful Western and buddy movie, starring Paul Newman, Robert Redford and Katharine Ross, and loosely based on a true story.

Not the much-loved original, but a worthwhile 2010 remake starring Jaden Smith and Jackie Chan that retains all its important elements.
Pretty good for some father and son bonding.
