Considering that the age range of the UT audience is probably a Bell curve with most people grouped around (I'm guessing here) between 30 to 55 years old plus some people between 20 to 30 and some over 55. If you calculate that somewhat limited span the odds are not that overwhelming against it.

I've noticed our choir has a definite bell curve of voices: few at the bass and soprano ends, and a huge rump of tenors, trailing off slightly towards the altos.
