I think Glee...
I'm new to this site, and I don't know if they have talked about, or somebody else brought this up, but I think Glee should do a Grease and / or Abba episode. Personally, I think Rachel and Finn would rock "Lay All Your Love On Me", and I could really see some of them singing "Summer Loving" or "Take A Chance On Me".
Who else agrees?
Sorry if I brought this up again or whatever. :P
That would be amazing.
Although they have already done some Grease, so maybe Abba.
You can all laugh at my daggy taste if you like, I don't mind.
