I Let My Mind Wander

I let my mind wander
And what did it do
I just kept right on goin'
Until it got right to you
Can't trust it one minute
It's worst than a child
This old face without conscience
And it's driving me wild
When I let my mind wander

I try to keep my mind busy
With thoughts of today but
In terrible memories
Seem to lure it away
My lonely heart wonders
If there'll ever come a day
When I can be happy
But I can't see no way
Cause I let my mind wander
