The audio appears to be from the Island released VHS "The Best of Free".
I'll Be Creeping & Songs of Yesterday were both recorded at the ITV Granada studios. My Brother Jake is a most likely the studio recorded audio, which was then used to overdub the promo video along with added audience noise.
Fire & Water was filmed at the Beat Club in Germany. It has since been made officially available.
