UPDATE No 2.

A link to this blog has been posted at bowiewonderworld, and the knowledgeable folk there have pin-pointed some errors in dates and venues. So heres correcting them:

1972 07 14 London The Queen Of Kings Cross.
This is in fact a fake and is compiled of other 1972 recordings. For this information i thank Rubbishness/Kentish.

1972 07 18 Aylesbury This Boy.
It seems Bowie never played Aylesbury on this date and this is in fact Bristol 27th August 1972. For this information i thank Rubbishness/Kentish.
