How many male a cappella singers does it take to mesmerize two teenage girls? Answer: Nine.

Last night after the Vocal Point  concert (a nine-member male a cappella singing group from BYU who recently appeared on the NBC show "The Sing Off")

Maddie (excited to the point of giddiness):  THAT.  WAS SO.  AMAZING!!  I'm never going to forget it!

Aimee:  I'm swooning.
