Probably a chart return shop, like my old local shop.It was W H Smiths - i did go back, girl was nice and for some reason the branch i used seemed to get the limited edition free single versions (UB4O, Dr Feelgood and such like)
Several JM CDs were actually HDCD encoded. Playing back on a normal player is not ideal, some loss of dynamic range mainly.I only had Court and Spark on CD for years and thought it one of Joni Mitchell's weaker records.
