Robin Thicke is still trying to get his wife Paula Patton--with the help of a song.

Thicke was performing in Atlantic City when he covered Al Green's "Let's Stay Together."

Thicke first paid tribute to Paula last week at his show in Washington D.C. That was where he sang his 2007 track, "Lost Without U," which was inspired by Paula Patton.

No comment from Paula or her camp.
