First recorded by The Regents (US #13/R&B #7 1961).
Also recorded by Jan & Dean (1962).
Other hit version by The Beach Boys (US #2/UK #3 1966).
From the wiki: “‘Barbara Ann’ was written by Fred Fassert and was first recorded by The Regents as ‘Barbara-Ann’. Their version was released in 1961. It reached #13 on the Billboard Hot 100 chart, and crossed-over, too, as a Top 10 R&B hit. The Beach Boys recorded their version on September 23, 1965 (five days after actress and model Barbara Anne Feldon coincidentally made her first television appearance on Get Smart). Dean Torrence is featured on lead vocals with Brian Wilson. Torrence was not credited on the album jacket but ‘Thanks, Dean’ is spoken by Carl Wilson at the end of the track.
“By late January 1966, ‘Barbara Ann’ was in position to replace ‘We Can Work It Out’ by The Beatles as the next #1 song. However, ‘My Love’, by Petula Clark, unexpectedly vaulted into the #1 position the week ending February 5, 1966. Consequently, ‘Barbara Ann’ peaked at #2 in the US Billboard Hot 100.”
