I've started playing the song that Jim Dixon posted. Here are the chords that I use:

[C] Rufus Johnson Snowball Lee was [F] known both [G7]near and [C] far
To be the greatest ladies' man u[D7]pon a private [G7] car.
He [C] had a gal in [C7]ev'ry town who [F] met him at the [Cdim] train,
And [C] when the boss was [A7] out of sight,
To [D7] her he [G7]would ex[C]claim:

   Come right in, [A7] sit right down,
   And [D7] make your[G7]self at [C] home. [G7]
   You've [C] found the place you're [A7] looking for;
   There's [D7] no more need to [G7] roam.
   I [C] know you're hungry; [C7] eat your fill,
   For [F] Mister Pullman [Cdim] pays the bill,

COME RIGHT IN, SIT RIGHT DOWN. . .


   So [C] come right in, [A7] sit right down,
   And [D7] make your[G7]self at [C] home. [G7]
