Bob Ufer Soundclip
I could probably do this on my own but I have no idea how to do so without a lot of google-fu. I was hoping that somebody might have a soundclip of Ufer saying "Touchdown Michigan". Nothing more. If anyone can help that would be greatly appreciated!
You can find a bunch of clips here.
Here's the famous "Touchdown, Billy Taylor" clip from 1971:
is the best place I've found for his sound clips, but it sounds to me like you want a ringer tone possibly? If you're talented enough you can take one of those clips and do some surgery on it, otherwise you may have to see if someone else has created a ring tone. Unless I'm WAY off the mark here...
No that is pretty much the idea. I haven't ever tried to download YouTube sounds and edit from there. I was just trying to save myself work if anyone else had already done something like this. Seems like to google I go!
