It was published in TV Themes by Wise Publications (1993) and this may still be available. It was quite inexpensive and had 18 numbers including "Open All Hours", "Only Fools and Horses", "It Ain't 'alf hot" and "Dad's Army".
I suspect that the reason you can not down load the second sheet is to force you to buy it as the copyright rules are strictly applied by sheet music sellers.
