@bassmangotdbluz You can also use G7 (instead of G) before the D since it acts as a "leading tone". That is frequently done in bluegrass & country tunes.
@hotwheels770 (verse) this will probably help: [G]Dooley was a [C]good old man He [G]lived below the [D]mill [G[Dooley had two [C]daughters And A [G]Forty [D]Gallon [G]still One girl watched the [C]boiler The [G]other weatched the [D]spout [G]Mama corks the [C]bottles When old [D]Dooley sets them [G]out (refrain) [G]Dooley, steppin' up a holler[C] Dooley, tryin' to make a dollar[G] Dooley, gimme a swaller[D] And I'll pay you back some[G]day
@hotwheels770 Capo @ 3rd fret (so you're actually playing in Bb) it's just I, IV, V very elementary or G, C, D if you prefer... you should be able to figure it out by watching him play it. I mean no insult; I'm guessing your a beginner because even a novice could play that progression without thinking about it. Watch his left hand; it's really simple.
