I play it in G. Here are the chords I use:

(G) Once I lived the (B) life of a (E9) millionaire
(Am) Spending my (E9) money, with (Am) never a care
(C) Takin' all my (Gdim) friends out (G) for a good (E) time
(A) Drinkin' high-priced liquor, (D9) champagne and wine

Same pattern repeats for the rest of the song.

Here are the chord fingerings I use:

G=355433   B=799877 E9=X76777 Am=577555 C=335553 Gdim=XX2323 E=022100 A=577655 D9=X54555

In the third line, it's nice to walk the G chord down to the E through F# and F. You can also substitute E9 for that E major.
