....one of my favourite bands from the 1970's was FOCUS....they were always overlooked as an elite prog band, but they had some of the best musicians of all time especially JAN AKKERMAN...one of the most talented guitarists who ever lived....THIJS VAN LEER is also amazing and still leads FOCUS....just found this clip of an appearance on "Don Kirschner 's Rock Concert ".....I've seen it before, but it's been a little while....
