Context: Shoney’s is a privately held restaurant chain headquartered in Nashville, Tennessee, United States.  Operating primarily in the South, Shoney's also has restaurants in the Midwest and Lower Mid-Atlantic states.  Founder Alex Schoenbaum became a licensee of Big Boy Restaurants (originally known as Parkette) in 1952.  Two years later the name was changed to Shoney's, and aggressive subfranchising followed.  Thirty years later, having outgrown its Big Boy territory, Shoney's dropped the Big Boy affiliation. Wayne Douglas McAllister (November 17, 1907 – March 22, 2000) was a Los Angeles-based architect who was a leader in the Googie style of architecture that embraced the automobile and the Space Age.

His 1941 El Rancho Vegas was the very first resort hotel on the Las Vegas Strip, and his iconic 1949 Bob's Big Boy restaurant in Burbank, California is a California historical landmark.  He created iconic circular drive-in restaurants in Southern California, including Simon's, Herbert's, and Robert's in the 1930s.

Sambo's is a restaurant, formerly an American restaurant chain, started in 1957 by Sam Battistone, Sr., and Newell Bohnett.  Though the name was taken from portions of the names of its founders, the chain soon found itself associated with "The Story of Little Black Sambo".  Battistone, Sr., and Bohnett capitalized on the connection by decorating the walls of the restaurants with scenes from the book, including a dark-skinned boy, tigers, and a pale, magical unicycle-riding man called "The Treefriend".  By the early 1960s, the illustrations depicted a light-skinned boy wearing a jeweled Indian-style turban with the tigers.  A kids club, Sambo's Tiger Tamers (later called the Tiger Club), promoted the chain's family image.

It appeared on The Lovin' Spoonful's 1967 soundtrack album "You're a Big Boy Now" and was released as a single, reaching #15 on the US pop charts.  In the same year, a version by Bobby Darin reached #93 on the US charts, saxophonist Bud Shank put the track on his album "A Spoonful of Jazz", and Billie Davis put it on the B-side of a single in the UK. Robert C. "Bob" Wian (June 15, 1914 – March 31, 1992) was the founder of the Big Boy restaurant chain.  The restaurant got its start in a 10-stool Glendale, California, hamburger stand in 1936 with an investment of $350 which Wian got from the sale of a used car.  He sold the Big Boy chain to the Marriott Corp. in 1967 for $7,000,000.
