Context: Wang Zhenhe (Wang Chen-ho, 王禎和) (1 October 1940 – 3 September 1990) is one of Taiwan's most famous writers.  Wang's masterpiece is the comic novel "Rose, Rose, I Love you"(《玫瑰﹐玫瑰我愛你》), which is set in the coastal town of Hualien during the Vietnam War.  The novel's plot centers on the efforts of the town's leaders to come together to set up a brothel to entertain a group of American GIs coming to Taiwan for R&R.  Wang is considered the foremost representative of the "nativist literature movement" (鄉土文學運動) that swept Taiwan in the 1970s and 80s.

In the 20th century it helped inspire blues, and it remains a staple in gospel music.

"The world" was what American GIs in Vietnam called the United States, and returning to it could be a harrowing experience; Mayfield addresses this problem in the title track.  The album also includes the minor hit “Future Shock," which was covered by Herbie Hancock in 1983, and the emotional "If I Were Only a Child Again."  "Back to the World" went to #1 on the "Billboard" R&B Albums chart and reached the top 20 on the Pop Albums chart.  The single "Right on for the Darkness" was featured in the 1995 film "Dead Presidents." 33 Beer was the name of a Vietnamese-produced beer (pronounced "Ba Muoi Ba" in Vietnamese, which means "thirty-three).  It became well-known among American GIs during the war in Vietnam in the 1960s and 1970s.  In 1975, when South Vietnam fell to the North Vietnamese, the communist government changed the name of the beer to "333 Premium Export Beer" in order to distance itself from its colonial origins.  It was prepared as a rice beer using rice.  It is now made by Sabeco Brewery. Rye India Pale Ale is a style of Rye Beer that has a strong hoppy character comparable to the India Pale Ale.

The Pennsylvania Railroad Depot and Baggage Room is a historic railway station located at 400 Center St. in Dennison, Ohio.  The depot was built between 1884 and 1900, and the baggage room was built circa 1912.  The depot is best known as the home of the Dennison Depot Salvation Army Servicemen's Canteen during World War II.  The canteen, which operated from 1942 through 1946, served refreshments to troop trains passing through Dennison.  Dennison native Lucille Nussdorfer proposed the canteen; the Salvation Army and a citizens' committee operated it under the direction of Salvation Army Captain Edward Johnson.  As Dennison was a division point on the Pennsylvania Railroad, every train that passed through Dennison stopped there; since the canteen workers vowed to serve every soldier passing through the station, the canteen ultimately served 1.3 million soldiers, 13% of the U.S. forces.  4,000 volunteers, the majority of them women from the surrounding area, worked the canteen during the war; the canteen was the third-largest Salvation Army canteen in the nation.  The canteen became well-known among soldiers, and its fame spread across the eastern U.S.; it appeared in newspapers as far away as Pittsfield, Massachusetts, was compared favorably to canteens in New York City and Chicago, and led Captain Johnson to become a recognizable figure on the East Coast.  Soldiers nicknamed Dennison "Dreamsville, U.S.A.", a reference to an ideal small town in a Glenn Miller song.
