Sinatra traveled to Vietnam to perform for U.S. troops in 1966 and 1967. Many soldiers adopted her song "These Boots Are Made for Walkin' as their anthem, as shown in Pierre Schoendoerffer's documentary "The Anderson Platoon" (1967) and reprised in a scene in Stanley Kubrick's "Full Metal Jacket" (1987). Sinatra recorded several antiwar songs, including "My Buddy", which was featured on her album "Sugar", "Home", co-written by Mac Davis and "It's Such a Lonely Time of Year", which appeared on the 1968 LP "The Sinatra Family Wish You a Merry Christmas". Sinatra recreated her Vietnam concert appearances on a 1988 episode of the television show "China Beach". Sinatra still performs for charitable causes supporting Vietnam veterans, including Rolling Thunder.
