The 'YES' Documentary (Part.1)

Recently I discovered a documentary concerning one of the greatest bands of the Progressive Rock scene of the '70's. I'm talking about 'YES', and in this 2-parts documentary you can see many
interesting things about them. Interviews, rare live footage etc.
The documentary is divided in 2 parts, and today I'll post the first one which has a running time over 90 minutes.
Tomorrow or the day after tomorrow I'll post the second part, so it will be complete.
So make yourself a coffee or a drink, sit back, and enjoy 'The YES Documentary'! :)
