(1) the sheet music in "Garcia" and "Anthology Volume 1" both have "Since it costs a lot to win." But Hunter's lyrics in "Box Of Rain" and the later "Jerry Garcia Songbook" both have "Since it cost ..." which seems to be what Jerry sang.
Since it cost a lot to win (note 1)
And even more to lose
You and me bound to spend some time
Wondering what to choose
Goes to show, you don't ever know
Watch each card you play and play it slow
Wait until that deal come round
Don't you let that deal go down, no, no
I've been gambling here abouts
For ten good solid years
If I told you all that went down
It would burn off both your ears
Since you poured the wine for me
And tightened up my shoes
I hate to leave you sitting there
Composing lonesome blues
Wait until that deal come round
Don't you let that deal go down
[repeat etc]
