I really like that Bullfrog! Is there anywhere/way of getting the melody?
I was also an ABC minor, remember the song? I recall the tune but I can only remember the last couple of lines;
"We're all pals together,
We're minors of the ABC"
and another line "and every Saturday we line up"
It was common practice to allow any child who's birthday it was to come forward on to the stage while the rest sang Happy Birthday.
Then the compare or cinema manager, who always seemed to be a large, silver haired, frustrated thespian type would go along the line, holding a microphone, while the Birthday boys and girls said thankyou;
"Thankyou very much, minors"
"thankyou very much minors"
"THANKYOU VERY MUCH MINORS"
and on it went down the line.
As you say, after the show, which was usually two feature films plus fillers long, we all poured out into the daylight riding imaginary horses and shooting with our fingers!
It's so long since I thought about that, Bullfrog, that I'd just like to say;
"Thank-you very much, minor!"
