Not all of song leaders pick songs to sing considering the instruments, which means sometimes you should be all-rounded, playing drum, bass, and guitar. But piano itself can make you be all-rounded.
When piano should take a lot of parts for other instruments, one important thing to focus is rhythm. I know many of us want to play focusing on melody but lets try to hold it in because rhythm always should go first.Especially this song splits rhythm a lot more than other songs so you should practice yourself a lot.
If your band has a lot of different instruments to diversify the song, you do not have to split it as much as I did. Guitar will be a good fit for this!
Thank you
