The Hollies at the San Remo Festival, February 1967. In the back-line, two AC100s, and two 7120s and cabs. The 7120s are on the stage floor in front of the cabs – presumably because the trolleys lack their top bars (ie. the section the amp would conventionally sit on). The side stands, however, are still in place.
This may have been a Vox sponsored event – Los Bravos are also pictured using the same equipment. One might be forgiven for conjecturing that the trolleys were damaged in transit from England.
