From the clips mish-mash of the intro I thought I was going to be disappointed, there were just so many, Frere Jacques and Floyd, Beatles, Marillion, The Smiths, etc etc did that so often...but...once the phased riff kicked in with its Tomorrow Never Knowsness it was cool and the break at abou 3 minutes in, really nice. Going heavy at 3'40" reminded me of the great Porcupine Tree. This is prog how it should be done in the 21st Century, tips at hat to the late 60s and onwards but that hat is not a feathered floppy felt hat it's the most stylish you can imagine...
Was disappointed that it ended...a sign of a really great song, have to go round again.
Love your mock html tags around the lyrics ;-)
