Does anyone know how to contact Paul Curtis the songwriter?

There have been two other people asking but I cannot respond to them as their questions are now closed. He wrote the music for one of my songs and I would like to contact him about it. If you know him, or of him, you can check it's the same one (as there are many responses to that name on the Internet) by seeing him in a video on YouTube (put "theargonaut" into the search box. I hope you don't mind Paul (if you read this!).
