Paul Burgess notes: "Round about the time City of Cardiff Transport were disposing (1988?) of their ECW bodied series 2 Bristol VRTs/Eastern Coachworks (PKG 586-605M), BBC Wales used one in a series called Juice. It was towed to the BBC Cardiff site, and used in a static role - CCT had retained its power unit! The series featured live studio performances of local bands (along the lines of the Old Grey Whistle Test), and the bus was used by the then unknown Magenta Devine for interviews and to introduce the bands. Most shots of the bus were lower deck interior, which was decorated in a very outlandish way. The exterior was mainly silver, with graffitti type decoration featuring the programme name Juice. I do not know which bus it was, but it definitely was not the sole survivor today, PKG 587M. The programmes were only shown in Wales, so further information might be scarce."
I believe this was 599 (PKG599M).
