On A.J.'s blog, there may have been a post or two from WindsofChange's website...here's one that basically gives Beaker Street the credit for starting "underground radio":
"...patterned after radio shows like Beaker Street with Clyde Clifford. That program, which aired on 50,000 watt clear channel station KAAY 1090 AM out of Little Rock Arkansas from 1966 through 1972, is considered by many to be the first "Underground" radio program. Although it aired on an AM station, it greatly influenced the "Free Form" and "Progressive" radio formats of the years that followed."
Many people WERE influenced by Beaker Street and it's still very popular. Whether it was your cup o' tea or not, it was an interesting, eclectic show. Many still listen today, via it's latest incarnation on the 'Web.
