This may be a little too punk for what you're going for, but '87 by the Bouncing Souls is another good one.
Good call!!
With a Little Help from my Friends by Joe Cocker (a'la Wonder Years!)
Closer to Fine by the Indigo Girls (this is actually one of our official chapter songs)
Higher and Higher- Jackie Wilson
Swing Life Away- Rise Against (again, may be a bit too heavy for ye, but if done right...)
I didn't read the whole thread so someone might have already mentioned this one, by my chapter has been using "Road Outside Columbus" by O.A.R. It's about going off to college and finding a home away from home. Our video typically starts with O.A.R., then has some sort of angel song, and then closes with "Feels Like Home."
My chapter was planning to use Esthero's Wikked Lil' Grrrls for the sisterhood/social video, which would've worked really well if we didn't have technical problems!
We are making a recruitment video this year and are wanting to make something professional. Does anyone know of a company or website who specializes on Sorority videos?
