Great article on the creation and legacy of the songs.
The Boston Garden tidbit is definitely new. He's referring to the Feb 9, 1977 show we've all heard now - the only time they'd played that venue at that point.
So the Sex Pistols were recording at Wessex Studios from February to September in 1977.
Do we know when in 1977, WWRY was recorded, other than "in the Summer"?
It would be interesting to know when Fred met Sid, since it was apparantly during the recording of WWRY that event occured....
From what I read, the Sex Pistols came in June and August to record their album. It seems Sid Vicious played bass only on the song they recorded in August. So WWRY recording and Freddie meeting Sid might have been in August.
