The Flintstones was groundbreaking in many ways. Among other things, it was the first cartoon series to include a laugh track and story arcs (e.g., Wilma's pregnancy.) The show was also revolutionary for its regular inclusion of guest star voices (Tony Curtis, Hoagy Carmichael, Elizabeth Montgomery, and James Darren, among others) and for its acknowledgement of and spoofs of pop culture icons and personalities. These included people like Alfred Hitchcock ("Alvin Brickrock") and Ed Sullivan ("Ed Sullystone") as well as TV and movie characters like James Bond ("James Bondrock") and Perry Mason ("Perry Masonary".)
The Flintstones also made a point to recognize and sometimes parody various pop culture phenomena taking place during the 60s, such as the British Invasion ("The Way Outs" and "Bug Music"), the beatnik movement, the country's space program, surfing craze, and even "The Twist" ("Twitch".)
One of the most unforgettable things about The Flintstones is its music, which incorporated everything from vaudeville tunes, to commercial jingles, to modern pop music. Around the time the first Flintstones movie was released in 1994 (and by the way, how badly did they miss the mark on that one -- thirty-two different writers and that's the best they could do?) I wandered into a long since defunct music store called The Wall and picked up The Flintstones: Modern Stone Age Melodies, which featured many of the most memorable songs from the show's six year run. The best of these include "Rockin' Bird" (from the episode where Fred becomes singing idol "Hi-Fye") and "Open Up Your Heart and Let the Sunshine In" (which was later covered by Frente'.)
As a bonus, the album also includes lots of dialog from the show, extra tracks consisting of instrumentals used for the show's transition and chase scenes, and background music.
I only wish Modern Stage Age Melodies included the two songs Ann-Margret performed when she appeared on the show in 1963 (the same year her breakthrough movie Bye Bye Birdie was released) -- "I Ain't Gonna Be Your Fool No More" and "The Littlest Lamb".
Margret was on Phil Donahue's show many years ago and she fondly recalled her appearance on The Flintstones. A woman in the studio audience then remarked on what a beautiful song "The Littlest Lamb" was and asked Margret to sing it, but she politely declined.)
