Four goals from Steve White and further strikes from Lil Fuccillo and David Moss completed the rout. The Hatters would end the campaign as champions of the old Division 2 (now Championship) and with it promotion to the top-flight.
The Town have won one and lost one against local rivals Watford on this date. A 0-1 home defeat in 1931 was followed a 4-1 victory at Kenilworth Road five years later.
Four years ago the Hatters won 1-0 at Altrincham thanks to a Tom Craddock penalty.
