"...Michael Giles and Ian McDonald felt they had to break away from the KC fold mainly due to musical differences with band leader Robert Fripp as well as due to constraints of touring. In fact the two left the band in December of 1969, during the US tour to promote their debut album...Because of this Fripp had to stop the tour and cancel all dates booked for January/February 1970."
