I have so many favorites, it's hard to keep a short list. Buy my favorites are It Hurts Me, You'll Think of Me, I'll Hold You in My Heart, Reconsider Baby (can Elvis sing the blues!!) and the TTWII live version of Just Pretend.
But most often I play his gospel, with some of my favorites being If I Can Dream, You'll Never Walk Alone, Who Am I, American Trilogy & Stand By Me. Stand By Me was particularly meaningful to me recently, as I was going through a time of dispair. I played that song over & over again, as every time I listened to it I was reminded that God is with me through the dark times.
With regard to the laughing version of Are You Lonesome Tonight, I heard an interview of Kathy Westmoreland where she talks about a man's toupee falling off in the middle of that song, which is why he is cracking up & add libbing. Then she went on to talk about in the early days of Vegas a gong was played at the end of You've Lost that Lovin' Feeling. Each night the gong got bigger, with this little Asian guy hitting the gong. Well on the last night, the gong was huge. They had not rehearsed the gong, and when little this guy hit it, the vibrations were so strong, it threw him into the orchestra pit. She said Elvis had a hard time maintaining his composure after that. Very funny story. The whole interview is very touching. I had tears at the end. If interested, it is on a DVD called Behind the Image Vol. 1 and you can get it at
