Errol Garner

I need help with arranging songs for a jazz trio competition on thursday!?
the trio consists of myself-piano, a violinist (grade
who plays jazz and her brother on drums.
We have to play 2 songs no longer than 5 minutes with improvisation included- and we have left it this late to practice. We are practicing on Tuesday, and Wednesday and have communicated by email until now. Her best song is ‘Summertime’ by Gershwins and my best song is Misty by Errol garner. I am grade 5 with 6 and above for theory and improvisation. The violinist has suggested Gypsy minor swing by rheindheart, making whopee and cole porter songs- all covered by stephane grapelli.
Do you have any advice for last minute practicing and organization- which songs should we choose (the songs we are best at or will be most impressive) and how do you play Piano effectively along to summertime?
Thanks. I know it’s a big question.
My two favorites are Stella By Starlight on piano and Estrellita on violin for pop tunes
Cant answer technical questions. Hope you get help.
