When I began my Directing career in the early 1980s for a period of time I FORBADE audition songs from "A Chorus Line", "Annie", "Pippin"and "Joseph...". Reasons: They were overdone; many performers presented their best imitation of the cast recording. I have often counseled performers that if they are auditioning for something from the catalogue of the classic American Musical, review the canon of the Composer/Lyricists' and chose something from a DIFFERENT score of theirs than what you are auditioning for and try to find a song that is typical of the character you are auditioning for, ex. Ado Annie from "Oklahoma!" use something of Carrie's from "Carousel". Also, songs from less frequently produced shows sometimes draw more attention. I once had a young male performer come in and sing one of Brenda Vaccaro's songs from "How Now, Dow Jones". He was certainly remembered at casting time and worked for our theatre company for over 10 years.
