When someone has left you blue
And you don't know what to do
Or when your love life goes astray
And you're restless night and day
Join a lonely heart my friend
Knock three times and come on in
When your blues are here to stay
Every hour, every day
And your dreams all fade away
And your heart has gotten pain
Oh join a lonely heart my friend
Knock three times and come on in
When you have no more tears to cry
And you can't smile although you try
And if you're lonesome as can be
And you need some sympathy
Just join a lonely heart my friend
Knock three times and come on in
When you have no more tears to cry
And you can't, no you can't smile although you try
And if you're lonesome as can be
And you need some sympathy
Come on and join a lonely heart my friend
Just knock three times and come on in
Join a lonely heart my friend
Knock three times and come on in
