How Long Has This Been Going On?

How Long Has This Been Going On? - George Gershwin
I could cry salty tears
Where have I been all these years
Little wow tell me now
How long has this been going on
There were chills up my spine
And some thrills I just can't define
Listen sweet I repeat
How long has this been going on
Oh I feel that I could melt
Into heaven I'm hurled
Now I know how clombus felt
Finding another world
Kiss me twice then once more
What a dunce I was before
What a break for Heaven's sake
How long has this been going on
How long how long how long
