Hmmm,I don't think you're going mad but I think you've probably made a mistake.
I checked the official site ( a href="www.jamestaylor.net">www.jamestaylor.net ) and the comprehensive looking unofficial site ( www.james-taylor.com ) which Spaw mentioned, without any luck. The unofficial site also includes a long list of bootlegs, but nothing there either.
Sorry for being no help, but are you sure?
