You probably know that Pete Townshend covered that song. At the time, David Gilmour was in his band, and they were trying to figure out the tuning to use, and they couldn't figure it out. So, they called up Dave Wakeling, to ask him how he tuned the guitar for the song....LOL, imagine getting that call, from Gilmour and Townshend.
I was aware but thanks for sharing it’s a fun story.
