Instead of Pepper for the 1st class rate, it would be better for the 64p rate, as in "When I'm".
Please Please Me and With the Beatles should be 1st and 2nd, of course.
For the same reason, the US missed a golden opportunity when issuing a Jack Benny stamp years ago. When the 2 ounce rate was 39 cents, his stamp was at the regular rate of 22 cents for a single ounce, iirc.
For those too young, he always claimed to be 39 years old in his act.
