Question

There is a show on at my school next Friday and I'm in it. I'd love it if you could come.

In this sentence can the word 'on' be omitted

Answer

Yes, in American English, you can omit the word "on".

(People from other English-speaking countries may have other opinions)

Good luck!

Answer

Yes. Omit 'On'.

Then it sounds like American English.

Or you could say....

I'm in a show at my school next Friday. I'd love it if you could come.

Or...

I'm in a show at my school next Friday. I'd love to see you there.

Answer

You can omit it. Better ways to say it:

"There's a play at my school next Friday"
"There's a play on stage next Friday at my school"

We don't use "on" very much for shows in the U.S. but we say "on stage", "running", "showing", "playing".
