Good idea. The whole oevure of "Senior Snatch" comes to mind (whatever happened to Smeege?). There is a lot of material to choose from, though, and you would need to be selective. Most of the one hit wonders are such for a reason. Can't perform, bad look, or turned up in a dumpster the next day. The vast majority are probably local dancers/VIP Extra queens who decided to take the next step but lacked the drive, firm breasts, or bus fare to make it to the next level. Many would probably be quite happy to be reminded of their past glory, back when they had teeth and could command more than $20 dollars from truck drivers on Rte 13.
