Playing Piano By Ear

Hello Dave,

Thanks for your help via email, by the way... okay, here's my question. Firstly, I have taken myself through "How To Play Piano On All 12 Keys Without Knowing How To Read A Note Of Music" and I am working on playing a little song by ear in a couple of different keys. This song also only has three chords (Cmaj, Fmaj, and Gmaj)... How can I know immediately what note to start on in each key?
