WHEN THE ROSES BLOOM AGAIN
Recorded by Jim Greer and The Mac-O-Chee Valley Folks
Stars of the W.W.V.A. Jamboree

CAPO: 3rd FRET/KEY: F/PLAY: D
[D] They were strolling thru the gloaming as the roses were in bloom
A soldier and his sweetheart fond and [A7] true
And their [D] hearts were filled with sorrow
As their [G] thoughts were of tomorrow
As she [A7] pinned a rose upon his coat of [D] blue.

Do not [G] ask me love to linger for you [D] know not what you say
For duty calls your sweethearts' name a-[A7] gain
And your [D] heart ye not be sighing
If I [G] be among the dying
I'll be [A7] with you when the roses bloom a-[D] gain.

CHORUS
When the [G] roses bloom again beside the ri-[D] ver
And the Robin Redbreast sings his sweet re-[A7] frain
In the [D] days of Old Lang Syne
I'll be [G] with you, sweetheart mine
I'll be [A7] with you when the roses bloom a-[D] gain.

REPEAT CHORUS

TAG: I'll be [A7] with you when the roses bloom a-[D] gain.
