"All Or Nothing At All" by the Harry James Orchestra (with featured vocalist Frank Sinatra) was recorded in 1939 when Sinatra was a mere 24-years old. It was released at that time but failed to make the charts.
During the musicians' strike of 1943 (when vocalists were forced to record 'a cappella' or record outside the USA) the song was re-released and skyrocketed to #1, due largely to Sinatra's burgeoning stardom and popularity with his new band, The Tommy Dorsey Orchestra.
It was Sinatra'a first #1 hit (but certainly not his last!).
