That is what I ended up doing. As soon as one dance ended, I moved over 
to the fiddler, showed him the card, told him what I was thinking in 
order to give him the maximum amount of time to work on selecting tunes. 
Of course calling dances like Chorus Jig makes tune selection a little 
easier... 8^) In the end, I didn't keep the dancers waiting much after 
the walkthrough.

  One thing you could try - which would work for some

 at all for
 others - is to, just as soon as the applause dies down for the last 
 dance, hand
 him the card you're going to call the next dance from. (Or, as someone 
 else
 suggested, start discussing the character of the tune you want.) Then 
 the band
 can work on tune choices even before you start teaching.
