Might have found a connection with The Big Chill and Psycho.... will post if I can gather more information. 
			EDIT: Alright - here it goes, with some huge help from HHNManics. 
			"The Big Chill" (ST) features several connections to themes found in Hitchcock's "Psycho" 
			- "I heard it through the Grapevine" was written by Norman Whitfield.
			- "My Girl" features the lyric, "When it's cold outside, I've got the Month of May" (Mother's Day is in May)
			- Marvin Gaye's "What's Going On" alludes to Marvin talking to his mother when questioning what is happening around him. 
			So... thoughts?
