I can't believe either of the teams didn't get the Sgt. Pepper album cover clue, considering that one of them was into Pink Floyd and presumably would have heard of The Beatles.
I got that on the first clue (!!), with the mention of Huntz Hall - a name you are unlikely to forget, especially as he was this young sprog's hero on Saturday Morning Pictures, when I wanted him in our gang.
Also, he was involved in a far more interesting bit of trivia than who wasn't on the album cover......................EVEN WHEN the fourth clue was revealed as "Madam Tussaud's The Beatles next to The Beatles", it was only when the first team had a second stab at it and FINALLY got it right. Dear oh dear.
Huntz Hall was one of the lead characters, along with Leo Gorcey in The Bowery Boys films and were very big film stars at the time (1940s), especially in "Saturday Morning" pictures at your local cinema - so presumably they were, with the young pre Beatles John, Paul, George and Ringo as they wanted to include their photos on the Sgt. Pepper album
Both (Huntz and Leo) were happy with that, and permission was given, BUT Gorcey wanted a c. £300 fee, which was refused and so along Adolf Hitler, Jesus Christ and Gandhi he was not used. Not that they wanted a fee!!
