It's Been a Long, Long Time

"IT'S BEEN A LONG, LONG TIME
Bing Crosby with Les Paul/Harry James
words by Sammy Cahn, music by Jule Styne

Peaked at # 1 in 1945
Competing versions charted that year by Harry James (#1); Charlie Spivak (#4);
and Stan Kenton (#6)
- World War II ended the month before this Crosby recording hit No. 1 on the
Billboard charts in 1945. Accompanied by Les Paul on the guitar, Bing
effectively captures the swelling anticipation of Americans regarding the
imminent return of their boys from overseas. The song remained on the
charts for 16 weeks"
