[please excuse me if this question has already been covered - I did search this thread but didn't find it]
In Part 1, what is the film footage being shown of the band playing when their debut album is being discussed? It's not the BBC performance, but it looks like the same time period - possibly a filmed rehearsal? The boys perform Silver Dagger [when talking about Glyn Johns deciding he wanted to work with them because of their remarkable harmonic vocal blend], PEF and Witchy Woman.
The other bit looks like a television show performance. The band is playing Tequila Sunrise; in the background are large wooden wheels.
Thank you!
