“So Happy I’ll Be” is a bluegrass gospel song written by Lester Flatt and Earl Scruggs and recorded by their Foggy Mountain Boys around 1950, in the duo’s early years.
The lyric looks past the troubles of this world toward the joy of heaven — the believer’s confidence that, whatever the hardship now, he will be so happy in the life to come. That hopeful, forward-looking sentiment, set to the band’s bright, harmony-rich sound, was a familiar register in bluegrass gospel.
The song held a place in the Flatt and Scruggs sacred repertoire and was revived by the Bluegrass Album Band, the all-star group whose recordings revisited classic bluegrass material.
