well then I would change, "will they come to my day" to "would they come see me play" still rhymes same amount of syllables and it means exactly what you want it to mean. No need to write it in a weird way if you don't need to.

The way you have it now just doesn't really make anysense that's all. It could be several other things really, they just need to make sense if you are actually writing about something.

ideas (slight variations really):

"will they come hear me play?"

"would they come on the day, I play?" (i figure if it's a push then you can extend it just a little more for a more dramatic effect).

"blush now shucks off grapes" (grapes has the "A" sound in it so it rhymes just emphasis it when you sing)

There are a million possibilities really. anyway I don't mean to pressure you into changing your song I'm just trying to help out by giving you some ideas to expand on.
