This is a wonderful clip from a 1970 NBC TV special featuring many celebrities of the day singing "God Bless America". I am not the first person to send this to YouTube; it's been floating around for a little while. My contribution is to add chyrons (names) identifying each of the singers, as it is my strong belief that many out there will not recognize them all. I have added the birth/death dates of those who have passed on, but added no dates to those still with us. I cannot conclusively identify the African-American man at about 0:47 (seen in the thumbnail), but I believe him to be Paul Reid Roman (March 23, 1936 -- November 17, 1991).
The Movie was Called Swing, Out Sweet Land
