I thought the point was
there's "A" letter missing...

Shhh!
Once I sing the letter, it is no longer missing. Don't have me singing the letter in secret, because then it's only HIDING.

Ah
I suppose it depends where you put the emphasis.

Your emphasis is on "A letter" whereas I think the song tells you there's a letter missing. It is the letter B.

And I'm sure this exists other than in Manic's mind as I've heard it before.

Then we have a clear case of mindpiss
or someone is singing one of my "I am drunk enough to sing" songs without permission
