Well, the author can actually be a LOT younger than you (and me) @tbm3fan - because "groovy" came back into the trendy lexicon with the release of the Austin Powers movies (starting in 1997). And I think the "Swinging Sixties" term was also tossed around in that franchise (as the time period was supposed to represent the '60s). So, when I see "groovy", I harken back to Flower Power, Haight-Asbury, Peace Signs, and Pop Music - stuff from 1968 lingo. But someone who was in High School in 1998 - 30 years later - might actually recognize and use the same phrases simply because they were a fan of the movies! As they sometimes say, "everything old is new again"... 😃
As a fan of Jazz music from the 50s and up, I find the word groovy to be appropriate for the era. Yes, I am just a Gen X-er, but there were plenty of hip cats in the jazz scene that seemed to use it???
True Dat, @Sajeev. But in the jazz arena I suspect it had a context more related to music than in either the Hippie days or the Shagalicious world of Goldmember. As in, "that cat really gets in the groove with that slap bass!" Which sort of morphed into, "that Saxman is groovy!"
