Speaking of my gym teacher...here is another of his favorite songs of I think 1968. He loved Sam and Dave's I Thank You
Here is a bit of bio from Classic Bands.
Samuel Moore and David Prater were both raised in the Southern United States, where they sang in church as children. During the '50s, they performed in soul and R&B clubs with the gospel groups The Melionaires and The Sensational Hummingbirds, respectively, before meeting each other in at the King of Hearts club in Miami in 1961. Moore was hosting an amateur-night contest where Prater was singing. Once, Dave forgot the lyrics to Jackie Wilson's "Doggin' Around," Sam coached him through the song. Following that night, the singers agreed to work as a duo and soon became a popular local Miami act and signed with Roulette Records, releasing a handful of unsuccessful singles before being signed to Atlantic Records in 1965. Atlantic persuaded their Memphis affiliate, Stax Records, to produce them.
During the '70s, Sam & Dave reunited several times to little attention. At the end of the decade, John Belushi and Dan Aykroyd's Blues Brothers routine, which borrowed heavily from Sam & Dave, sparked a resurgence of interest in the two, and the pair performed a number of concerts during 1980. However, their personal animosity had not faded, and they separated after a performance on New Year's Eve 1981. For the next few years, Dave Prater toured as Sam & Dave with vocalist Sam Daniels. During the mid-'80s, Sam Moore revealed the sources of the duo's tensions in a series of interviews. Moore disclosed that he had been addicted to drugs during the '70s.
Dave Prater met with an even worse fate when he was killed in a car accident near Sycamore Georgia, on April 9th, 1988. Moore went on to appear with Junior Walker in the 1988 film "Tapeheads" and enjoyed a renewed solo career in 1994 when his duet with Conway Twitty, "Rainy Night In Georgia" appeared on the Top 10 crossover album "Rhythm, Country, and Blues". He rarely played on the Oldies circuit, but continued to record with the likes of Don Henley and Bruce Springsteen, as well as hosting his own show at Boombox Radio.
Sam and Dave were inducted into the Rock and Roll Hall of Fame in 1992.
