I never heard the song before...but know the dancers in the various clips compiled to create the "choreography". Whoever put it together has more than a little familiarity with dance as the steps match the beat exactly. I wonder at the time and patience taken to search through old movies to find just the right segments to match.
Glad to see you here! Things are getting back to normal in my life. My husband is almost fully recovered from his bypass and seems to have more energy than he's had in years. I was sorry he had to go through that experience, but I suppose it's better they caught the blockages before they became a problem.
Now that things have calmed down -- we went back to enjoying his retirement!
