There was another thread about a year ago relating to this common ragtime chord progression. With slight variations, it crops up in countless songs, and uses the cycle of fifths, ie seventh chords that each lead into the next (eg E7, A7, D7, G7), and can be found in jazz standards like Sweet Georgia Brown, and dozens of country blues songs by the likes of Blind Blake, Bind Boy Fuller, Willie McTell, Lemon Jefferson, etc. However, don’t let me kill off the thread, because I too would be interested to hear of more examples.
