Attention Fools and Horses fans, possibly the most important Trotter related post you will read all year.
The latest addition to my massive collection of rare footage. Recently discovered sketch featuring Del, Rodney and Grandad from Russell Harty's 1983 christmas special. To my knowledge this has not been seen for almost 33 years. Enjoy.
