Fourty years ago this week, "Keep on Truckin" by Eddie Kendricks was the number one song on the pop charts. It was the only solo recording by the co-founder of the Temptations to reach number one.
Truckin' was a dance step that became popular in Harlem in the 1930s. Kendricks once said about this song "I knew it was a hit because of the title. The old people used to truck when they were dancing. And I knew the trucking industry would embrace the record." To make that connection stronger, truck driving sound effects were added to the mix.
