The funny thing is, when "Bustin Loose" came out, there was no such thing as "go go" as we know it today, nor the DC Groove, nor the DC Beat. We were still in the Funk era. With Chuck Brown's band named "The Soul Searchers", this was still considered a Soul or R&B song, although this song really gave "go go" it's first boost. This is why Chuck Brown wound up with the name, "The Godfather of go go".
I remember in 79', the year 'Bustin Loose" came out, we did use the term "go go" for house parties. But it wasn't associated with what later became the go go sound. I first remember "Go Go" on television being a White term, used for young White people partying in the mid 60's. The TV show "Gidget", starring Sally Fields, was based off their "Go Go" era. During this time, we had to copy everything from White people, including their American Bandstand dances, because you rarely saw Black people on television. Being a little child, the only connection I remember having with Go Go, was Smokey Robinson's "Going To A Go-Go". Since we had to copy everything from White people, our teenagers and young adults back then may have temporarily used the term "Go Go" as well for house parties, as far as I know. I guess that's why the Black version is spelled "go go", to distinguish it from the mid-60's "Go Go" time frame, when you saw a bunch of young White people dancing at the beach on beach movies, like the one starring Frankie Avalon and Annette Funicello, where they were doing "The Twist".
But I still don't know why we used the term "Go Go" in 79' for house parties, and why the DC Grove, and The DC Beat later became "go go". I guess it was because Chuck Brown had reclaimed the sound from Trouble Funk, Experience Unlimited, and Rare Essence, and he was around since the early 60's, even though he really liked playing jazz. But that still don't explain why we were using the term "Go Go" in 79, when George Clinton and the Parliament Funkadelics still ran the show. How Chuck Brown reclaimed the sound may explain why we call it "go go" today, but it still don't fully explain why we were going around as high school teens on Friday nights, asking "Where's that Go Go?". It was a little wild during those days, but we had a lot more love for one another, compared to today.
