As much as it'd be an amazing and successful endeavour, It's my opinion both Haley and Casey, at this time, want to see where they can go on their own volition, with the occasional collaboration project
They've got time to tickle their Jazz Duo fancy, further down the road if they want.
I can't say enough how I love that Michael Slezak is an #OGHalien, he waves that flag loud and proud
Sure other Idol critics have written about the Idol injustices brought on Haley, but Michael has put Haley at the front, been in full support, verbally, litterally, and yes financially.. don't forget he bought into SMYM video, has promoted her PMJ collaborations, on top of sneaking in references to her projects every once in a while whilst doing his job
