It's THAT time. The music is good. All vocal chords are nicely lubricated; perhaps marinated is a better word. Once the first person starts singing along with the iPod it's like watching dominoes fall as the others join in. If there's harmony, it's more like an aural Rube Goldberg Variation. As much a vocal train-wreck as it is, it is also pricelessly entertaining. I love my friends. I love tradition.
