The Hollies on TV in Croatia, some time in 1968.
Three things immediately come to mind.
1. It is actually possible that The Hollies were staying at the same hotel as Mel Brooks, who was filming The Twelve Chairs in Yugoslavia at approximately the same time.
2. The Hollies probably had nothing to do after the show because Tito had the car.
3. This performance, although musically impeccable, is really kind of embarrassing. I mean, I had no idea that The Hollies were so totally a cabaret act at this point. No wonder Graham Nash was so hot to jump ship to Crosby Stills and Nash.
