Most all the songs played from the stands are about Texas. There are a handful or so of traditional tunes that have been around forever. If you can provide more info, I'll tray to help. Was in LHB many years ago. Or, if you know about when the song was played, contact the band office. They would likely know what was played and when.
It's really cool to hear Led Zeppelins' Kashmir played a coupla times when the D was on the field; at least from the vantage of TV - can't imagine godzillatron is responsible, but maybe so.
