Let me see... my favorite "good bye" song is the one that
Isn't Being Screamed Into My Ears!!!!! Nothing says "don't pledge here" like a migraine!
As for actual songs, the ever popular Linger is nice, but we did a peppy one for the round before pref:
Bye bye! Bye bye!
Wipe a tear Baby dear from your eye!
We hate to see you go!
You'll soon be back, we know!
Don't sigh, don't cry!
Won't do to be blue A D Pi!
Cheerio ring-ding
Bon soir we sing
Boom da de boom Bye bye!
It's so corny that it's catchy!
