Singer and melody writer

A couple of old guys have decided to get together and create a small recording studio. A keyboard player, programmer and a guitarist vocalist. Back in the day we created songs that were a pop rock hybrid and we would like to find singer/s who would like to collaborate simply to write songs and record. Our sound spans the decades and isn't pigeon holed. We are particularly interested in someone who can take a fledgling backing track and create a catchy melody line/hook. This would be something that could be a side line perhaps and wouldn't need a huge commitment. Music can be exchanged online to work from home and then the occasional recording session. What would happen to that music would depend on how well the project pans out. Any age and sex welcome to participate
