My school is really likely doing Grease next year and I would totally just about die to be cast as Rizzo. I heard someone say that I should do a "bad girl" monologue and a song in the vein of "There Are Worse Things I Could Do".

I already have my monologue, one from Chicago, but the song is a tough spot. The only one I can think of that's in a similar vein is "I Know The Truth" from Aida but somehow I think that's an overdone piece. However, I'm not sure if the same rules apply as to what's overdone in high school theater vs. professional theater?

In case they do, I need help to find some other material. The only thing I can think of that's like the songs I've mentioned is "Secondhand White Baby Grand" from the TV show Smash but I don't think I could find sheet music for that since the show is fairly new. Also, I'm not sure if a high school drama teacher would accept a song that wasn't from an actual Broadway show even though mine has accepted Disney songs and pop/rock ones that Glee's covered.

With that in mind, I need help as to songs for Rizzo and if I should go for a sexy monologue and dramatic song or vice versa.

Since there aren't a lot of other 50's/60's feel musicals, I'd suggest a pop song from the 60's, specifically "You Don't Own Me" by Leslie Gore.
