"I'm curious as to what songs/scenes were cut as a result of numerous people being out."
Dottie - No scenes or songs are EVER cut. They do, however, cut tracks when there aren't enough swings to cover. I've seen this quite a few times.
Tammy and Lou Ann aren't the only roles that are sometimes played by a Tommy or Louie. Shelley can be a Sammy. I think Brenda would be the only white ensemble girl that cannot be played by a man, unless someday it is possible for a man to get pregnant.
Hairspray has 2 white female swings: Gretchen Bieber and normally Michelle Kittrell. Michelle, however, is on a leave of absence doing the Legally Blonde workshop, so Cameron Adams has been the other white female swing. Cameron, however, was not there on the day in question because of an injury. Julie Halston was also out, so Lindsay had to step in to play Prudy, plus Donna Vivino was out, leaving two white ensemble girls out and only one female swing to cover. Because Shelley does have a bigger part, it was better to replace Tammy with Tommy, which is what happened.
As far as a white swing playing one of the black ensemble characters, this only happens in scenes where they absolutely have to have a certain number of people there, otherwise they just cut tracks out. For example, Terita Redd's track (Lorraine) is usually cut when there are two black girl ensemble members out (since there is only one black female swing), and one of the white female swings will come in just for the finale to cover the track so that there are no missing dancers. The same thing happened here: obviously the black male swing (Abdul Latif) was out, or was covering another missing black male ensemble member, and they just didn't have enough to cover, but they needed to have a certain amount of people in the detention scene, and it wouldn't matter that he's white...he's just another guy in detention. Had the white guy been at the record shop, that would've been another story.
Just because they have one black swing for each gender and two white swings for each gender doesn't mean anything other than that there are more white characters in the show. Do the math, and you'll see that the white characters totally outnumber the black characters, which means that more white swings are needed. 99 times out of 100 having just the one black swing in each gender has been enough. So ozone20, don't take it so personally as some kind of Hairspray racism. Having more black swings is unnecessary most of the time and would not be cost effective.
Sorry for the long post!!
