Thanks everyone for your kind welcome.
Starkeeper my dad has played accordion by ear in a band for the last 40 years, so i guess its a gift thats passed down.As for chords at the start i tended to play everything in C as i knew there would be a fair chance that i would be using C G F Am, then I bought a book that had the circle of majors and minors in it, I can now play in the key of Bb!!!!! The classes are helping big time.
Bebop i wouldnt know where to start with sending in a song, sorry.
