I was in grade school/middle school during Danderoo's first go-round on MNF. By the time he returned in 1977 (after 3 years beside Curt Gowdy on NBC) I was in 11th grade. As I was an eastern time zone resident (and always have been, even in college) and Monday night was a school night, I was never able, er, allowed to stick around for Don's song. Later on as an out-of-town college undergrad, I'd sometimes stay up in the dorm (and later on in my off-campus residence) to the end.
I never paid much attention to the Cosell/Meredith banter (or any of Howie's rhetoric). Although watching an ATL/WAS MNF game in 1972, when a turnover (I forget whose) happened early on in the game, Meredith sang "Sometimes you win sometimes you lose/Goodtime Charlie's got the blues" from the Danny O'Keefe song.
While at NBC, Meredith made TV movies and appeared on shows like "Police Story". Pete(r) Gent must've paid attention to that aspect of Meredith's career, too, because in the reunion sequel to ND40, called North Dallas After 40, the Meredith-like character became a TV actor.
No one mentioned the movie version of North Dallas Forty, starring Nick Nolte as the Gent-like character (Phil Elliott) and Mac Davis (who wrote songs like "In the Ghetto", "I Believe in Music", and had a #1 hit with "Baby Don't Get Hooked On Me") as the Meredith-like character (Seth Maxwell).
Meredith must've been one of the thinnest skinned football stars to have quit so young after so much booing.
RIP Don.
