"Mad TV" alum Lange (5)
I believe the answer is:
artie
'mad tv alum lange' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for artie that I've seen before include "Guy" , "Shaw, perhaps?" , "Man" , "- Shaw, US jazz clarinettist and bandleader" , "-- Shaw, jazz musician" .)
