It appears to me that this song is in the key of C major/A minor, so my question is just how does the E dominant 7 chord fit in to this key. Everything else in the song is diatonic with the key of Cmajor/a minor, which makes for a very easy jam, but what the hell is this chord doing in here. Dont get me wrong the chord sounds very ambiguous and i think that it single handedly makes the song but im just wondering what scales jerry plays lead in. Is there a key that im missing that has Fmaj (IV), Gmaj (V), Cmaj (I), Amin (vi), and Edom7 (III7)???
thank you
