Whoever Steve Perry chooses to do a duet with will reflect the style of music he is working on and
his intended audience. If he duets with Streisand, that is strictly adult contemporary. At least
the fact that he chose not to duet with Reba last year demonstrates he won't likely be jumping on
the country crossover bandwagon with Bon Jovi and Kid Rock.
The only female artist I am aware of that he has specifically mentioned wanting to work with is
Sarah McLachlan. She is currently writing, but not working on an album of her own which means
she is free at the moment...

What about Mariah Carey? She has a 5 octave range and is riding
high on her career comeback.
