Well, do you want to keep the song in it's current format or do you want to update the whole feel of it and make it more modern?
Cause what I would do is play the right and left hand chords in a way so that you are playing the music for the song and not just playing the song.
I'll see if I can post a video example later.
And playing that bass line while having a bass player is only going to clash. First thing you should do is learn your number system for which main bass note you should be on at which time and play that left hand chord. That would be the easiest solution
