March who hosted "The $64,000 Question" (3)
I believe the answer is:
hal
'march who hosted the $64000 question' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for hal that I've seen before include "Odyssean character" , "Prince -, Falstaff's companion (Henry IV, Pt I)" , "Falstaff's prince (H.IV)" , "Bluff Prince" , "Shakespeare's prince" .)
