You need to choose a cartoon character. You should also choose an activity for each letter of the alphabet.

For example:
A - All Mickey, All Mickey, All Mickey, All -- open your both hands and make the children enact all,
B - Bye Mickey, Bye Mickey, Bye Mickey, Bye -- wave your one hand to show bye,
C - Catch Mickey, Catch Mickey, Catch Mickey, Catch - enact catching

Continue with the other letters of the alphabet. This will help children to listen better and they do enjoy it a lot. It worked for me.

Sing it like a song!
