Wasn’t there some talk about how much of ‘Live and Dangerous’ was actually live? Seem to remember claims from some people involved with it at the time about the amount of overdubs etc.
The Who story about ‘Live at Leeds’ nearly being ‘Live at Hull’ surfaced a few years ago too. Apparently the band preferred the sound of the Hull gig ( the night after the Leeds one) but there were problems with parts of the bass recordings dropping out so they went with the Leeds gig instead. When they released the Hull gig 40 odd years later they used the Leeds bass recordings on some of the songs to fix this.
