Quick research clouds the claim of Georgia Tech having "stole" UWMB. Georgia Tech says "Up With the White and Gold" written somewhere between circa 1918 - 1920's by a band director of theirs. It is lyric heavy with enough words for two songs and the melody ventures off into the unknown. Also it shares school song recognition with "Ramblin' Wreck." Finally, there are not 2, but 3 schools using some version of the song - Cal has a pejorative version aimed at their trad rivals down the Peninsula with "Stanford Jonah." Frankly, Cal's rendition is truer to the sound of UWMB than the Jacket's.
There were waaaaay too many Youtube clips to list here, but you won't have a problem finding them.
