Lucky Man: Key G
Verses: G / D/F#bass
Chorus: A..Em..D
As for the lick at the tail end, it's based from D. It's easier to listen to it note by note, take it apart, and rebuild it to a playing form that you're comfortable with. There's a fair bit of joy stick work. If you sequence the lick...they will know.
Good Luck in your endeavours.
