Is this a good song to audition for Thoroughly Modern Millie?

Hey, I am going to audition for Thoroughly modern millie. I was at first going to sing "A little bit in love" from wonderful town but then I could not find the single song alone (i had to buy the whole book which i don't want to do) So I found, "on my own" from les miserables...Is this a good choice? I would either want Dorothy or Millie. Thanks!
