Sarah Vaughan - Speak Low (Live) 1959

Speak Low" (1943) is a popular song composed by Kurt Weill, with lyrics by Ogden Nash. It was introduced by Mary Martin and Kenny Baker in the Broadway musical One Touch of Venus (1943). The 1944 hit single was by Guy Lombardo and his orchestra, with vocal by Billy Leach. The tune is a jazz standard that has been widely recorded. The opening line is a (slight mis)quotation from William Shakespeare's Much Ado About Nothing (1600), where it is spoken by Don Pedro.
