Does anyone know this song played on a keyboard ?

Hello Cidyah, I'm sorry for posting here but i've been trying to reach you sir. Pls how I can get your contact. I try to mail you but I don't even see your e-mail address. I wanna ask you a couple things. I'm studying mathematics in college presently. You are my biggest role model after Leibniz. I wish I could understand mathematics the way you do and I think I can cause I love mathematics and have a lot of interest to know it. I've gone through almost all the questions you've solved on yahoo answers on maths, even the tough ones, you break them down., even on questionbox. Pls reply me, sir. My email is kolaoloke@yahoo.com. Thanks

Where's the song?
