I recently heard this reel(The Bush in Bloom) and am interested in learning it on the tin whistle but I can't find any tin whistle versions, I've found the violin, piano, uilleann pipes, and the flute but no tin whistle. I was wondering if anyone here was familiar with the tune or better yet knows it on the tin whistle.

Versions from other instruments should work fine on the whistle with only minor adjustments if necessary at all. there three versions on the session.org that all work in one way or another and all have the odd spot here and there as well.

There's a version on one of Catherine McEVoy's recordings, I believe. You could put that on the whistle without too much effort.

This should be a good starting point :

T: The Bush In Bloom
R: reel
M: 4/4
L: 1/8
K: G
