do you gaze at your bald head and wish you had hair

The arranged version of the song's lyric, by Elvis Aaron Presley(known as Elvis Presley). He performed the song called "Are You Lonesome To-Night?" in August 1969 at International Hotel in Las Vegas. The original lyric is "Do you gaze at your doorstep and picture me there", however he was in high mood, he apparently changed it to "Do you gaze at your bald head and wish you had hair". A moment later, Elvis noticed that a bald man in the front row took off his wig and swaying to the music.

Are you lonesome tonight,
Do you miss me tonight?
Are you sorry we drifted apart?
Does your memory stray to a brighter sunny day
When I kissed you and called you sweetheart?
Do the chairs in your parlor seem empty and bare?
Do you gaze at your bald head and wish you had hair?
Is your heart filled with pain, shall I come back again?
Tell me dear, are you lonesome tonight?

Shemp: You couldn't let me do it. You had to gum up the works.

Larry: Ah, go stick your head in a hornet's nest.
