In the shot of them with the three guitars and the champagne colored dresses, suddenly the song "Neutron Dance" popped into my head! Remember the three old broads who did an acoustic version of that while dressed in gold lame' who guested on an ep of "The Golden Girls?" I hate you for making it come to mind! lol
Tee hee! The fabulous Del Rubio Triplets are the three good time gals to whom you refer; sadly, I think all but one are deceased now.
The 188.8.131.52s are CLEARLY an homage to them!
