We usually do it to a tune played AB:
Traffic Jam
from John Krumm
no partner needed at start
1) Elementary Traffic Jam
A part:
Clap-clap-clap, stamp-stamp-stamp, walk-2-3-4 (whichever way you're facing)
Repeat all that
B part
Sashay sideways 8 steps
Pick another direction and sashay back
Do that for 5-7 times, then move to
2) Intermediate Traffic Jam
Turn around and find a buddy standing near you. Do the dance again. Instead of
clapping your own hands in A1, you clap both hands with your buddy, then stand
side by side facing the same direction, hook elbows and walk for the 4 steps. In
the B part, you take both hands with your buddy and sashay-- it helps if you
both go in the same direction!
Do that for another 5-7 times, then, if the crowd seems ready for it, do
3) Advanced Traffic Jam
Same as above, only after the first sashay, callers says "Switch!" whereupon
dancers drop hands with current partner, turn around and find someone new with
whom to sashay back again.
It's a dance I often use early in the program for family groups. No partner
needed at start, so everyone can participate. Then you dance with a partner, and
then change partners.
