From Bob Dearborn's The Olde Disc Jockey's Almanac, this little tidbit from 45 years ago today...
November 18, 1968…At the Troubadour in Los Angeles, Randy Meisner, Jim Messina, Richie Furay, George Grantham and Rusty Young debuted under the name Pogo, in honor of Walt Kelly's famous comic strip character. When Kelly later filed suit because of the name, the group changed to the similar-sounding Poco.
Meisner later joined the Eagles, Jim Messina paired up with Kenny Loggins, and Richie Furay started up Souther, Hillman, Furay band.
They were part of that California scene. In retrospect it sounds like lite-rock, but it wasn't considered that at the time.
