I am auditioning to become an entertainer! Mainly a singer and need 2 up to date audition songs for a female vocalist! Anyone any ideas? One needs to be a ballad and one uptempo!?

One, what type of audition is this for ? Is it for a actual night club ?
Is this one of the advertised "show cases " ?

But for any audition even professionals also use a vocal coach to help them for a few weeks prior.

No it's to be an entertainer abroad for a holiday company!

Think of the average age of the client for the company hiring. Pick songs from the genre of the people who could be there customers.
