this is where BIAB and RB shine, because they provide the tools to generate songs of commentary or celebration practically in real time. I expect a lot of such songs to go viral as people circulate them after news or sporting or political events.

Anyway, good job! It was a bit boisterous for my taste, but hey, it's about celebration! One change that would please MY ears: (others may see it differently) I would prefer that the sax drop out during vocals, then fade back in when the voice drops out. But the busy-ness introduced by the perpetual sax adds to the feel of an after-game riotous time, so it may well be the right design choice for this song, depending on the feel you want to create
