Camel - Another Night = Rare Live Music Video 1976 (76014)

I'm feeling like Another Night. Moonmadness is the fourth studio album by English progressive rock band Camel from Guildford.
 
"Twilight is fading through
Seems like I'm fading too
How can I believe it's real
When nothing starts to stop this wheel?"
 
The Phantom Four performing Another Night live in this rare music video. Speaking of progressive rock, which band of the last century comes first for you?
