From https://www.itsabouttv.com/2020/11/this-week-in-tv-guide-november-21-1970.htmlThis Week in TV Guide, 1970. Thanksgiving Day on the West Coast starts at 7:30 a.m. PT with my personal favorite of the era, The CBS All-American Thanksgiving Day Parades, three hours of fun featuring CBS personalities announcing four department store-sponsored parades: Macy's in New York, with Peter Graves and Julie Sommars; Gimbels' in Philadelphia, with Harvey Korman and Vicki Lawrence; J.L. Hudson's in Detroit, with New York Mets pitcher Tom Seaver and his wife Nancy; and, taped in Toronto,* the Eaton's Santa Claus Parade, with Mike Connors and Amanda Blake. For many years Bob Keeshan and the Captain Kangaroo gang hosted the overall coverage, but I don't know who (if anyone) was doing it by 1970.
