America (Paul Simon, 1968)
First released on their fourth studio album, "Bookends," in 1968, the song was later issued as a single in 1972 to promote the release of "Simon and Garfunkel's Greatest Hits." The song concerns young lovers hitchhiking their way across the United States, in search of "America," in both a literal and figurative sense. It was inspired by a 1964 road trip that Simon took with his then girlfriend Kathy Chitty. Biographer Marc Eliot wrote: "America" is a song that "creates a cinematic vista that tells of the singer's search for a literal and physical America that seems to have disappeared, along with the country's beauty and ideals." Marc Eliot, Paul Simon: A Life," p. 95 (John Wiley and Sons, 2010).
While the song was inspired by the 1964 road trip, Simon wrote the song in 1966 while in Saginaw, Michigan, after disc jockey Bob Dyer had booked him for "Y-A-Go-Go," a concert series hosted by the Saginaw YMCA.
The song has been regarded as one of Simon's strongest songwriting efforts and one of the duo's best songs. A 2014 Rolling Stone reader's poll ranked it the group's fourth best song.

God Bless The U.S.A. (Lee Greenwood, 1983)
Written and recorded by Lee Greenwood, it is considered to be his signature song. He wrote the song in response to his feelings about the shooting down of Korean Air Lines Flight 007. It first appeared on his 1984 album "You've Got a Good Love Comin'". It reached No. 7 on the Billboard Hot Country Singles chart when originally released in the spring of 1984; it was re-released as a single in 2001, re-entering the country music charts at No. 16 and peaking at No. 16 on the Billboard Hot 100 pop chart.
It was played at the 1984 Republican National Convention with President Ronald Reagan and First Lady Nancy Reagan in attendance, but the song gained greater prominence during the Gulf War in 1990 and 1991. The popularity of the song rose sharply after the September 11 attacks and during the 2003 invasion of Iraq.
It has been covered by many artists, notably by Dolly Parton and Beyoncé. The a cappella group Home Free has been performing the song ever since the band's inception in 2000, and in 2020, amidst the COVID-19 pandemic, they worked in the studio with Greenwood and re-recorded the song with him and the United States Air Force Band Singing Sergeants. The music video is set to release in time for the July 4 holiday. God Bless the U.S.A., Wikipedia.
