I have never been satisfied with the rhyme (often sung) that we use for the alphabet. The ending has always seemed lacking. So, I came up with this:
A, B, C, D, E, F, G;
H, I, J, K, L, M, N, O, P;
Q, R, S, T, U, V;
W, X, Y, Z;
Twenty-six letters with vowels we ply:
A, E, I, O, U and sometimes Y.

A fine rhyme. I watch Cop vids sometimes, and they always insist on the driver not singing the alphabet when they test them.
In Navy Boot Camp, we sing or chant what they term “ten general orders” quite a lot. When standing together “in formation.” When running together, also in formation.
Singing and chanting alone helps the memory better than reciting without singing. Doing it in a group, coordinated all together, as we did in Boot Camp, helps even more.
The Chinese still do that in their early classes, what we call Grade School. Mass chanting.
Undoubtedly some phycology stuff going on, there.
