I am aware Ken used to play a Conn 70H Single or maybe modified with a 2nd Valve.
Does any of the Pro's out there who were lucky enough to play with Ken to know what he may have used on this
particular recording, was it the 70H, or did he by any chance own and play a 73H ?
It would be great to know, if anyone out there could help.
