Good compilation, highly inept notes continuing the myth they split in the early 1960s, where in fact they toured heavily from 1963 to 1978 at least, if newspaper articles, adverts, and music industry publications are any indicator.
They were involved in 1960s television productions like Shindig! and Star Route, the latter of which filmed through late 1963 and 1964 in Canada and California.
They also went on several overseas tours in the 1960s, mostly US military bases across Asia and Europe. They played various nightclubs, casinos, fairs and rodeo events, and were even part of the infamous Dripping Springs Reunion country music festival in Texas in 1972. Dripping Springs was the same festival that Willie Nelson also played and used for the inspiration for his own 4th of July Willie Nelson Picnics.
