4 piece covers band doing all 70s 80s 90s and beyond

We are a 4 piece covers band based in South Auckland consisting of a singer, bassist, drummer and guitarist..looking for a savvy wiz on the keys to cover rnb, pop, rock, reggae, soul from the 60s to the 2000s. Our aim is to learn the songs and play live.. most of us have previous live experience. We are all in our 40s so would be nice to the age some one of a similar age, or younger just as long a you love playing the keys and finding those sounds.
