Yes, there is a whole story behind curtains.
During this show, Roger opened his performance with "I Feel Fine", and was part of the "My Sweet Lord" all stars finale.
"I Feel Fine" has *not* been recorded at all by the uploader, so don't expect it coming in the batch.
Part 6 is going to be uploaded soon and will contain Ringo's set plus also might include the finale, although only in partial form.
