Badass underrated instrumental from '66.....awesome hammond organ work by Ian McLagan.
It was a B side for one of their hit's on their 1st album, but was omitted from the release, and was eventually included on an anthology album 4 decades later.
In 1st year unversity a guy on my floor had some EPI towers. Huge fucking speakers, 6' tall and 4 sided, real air movers. An SAE 200 watts per channel amp too.
The big bass thump in Tank just about broke the windows in the concrete bunkers that were our rooms.
