"Don't Worry" is a song written and recorded by American country music artist Marty Robbins. It was released in February 1961 as the third single from his compilation album More Greatest Hits. The song was Robbins' seventh number one on the country chart and stayed at number one for ten weeks.[1] The single crossed over to the pop chart and was one of Marty Robbins' most successful crossover songs, peaking at number three on the Hot 100.[2]
In a 1968 report on sound effects in pop for Beat Instrumental, Crotus Pike believed the effect to be a result of the guitar being "played at a half speed", describing the resulting solo break as exhibiting "the tones of a rich, deep cello–a beautiful sound which no doubt attracted many buyers." He wrote that the effect was the opposite of the use of sped-up instrument solos used in other songs, such as Alan Price Set's "The House That Jack Built" and John Lee Hooker's "Walking the Boogie".[7]
