Cover of THAT'S WHEN YOUR HEARTACHES BEGIN in 1953 - first time he walked in at Sam Phillips' place to hear how his voice would sound; B-side of this unique walk-in facility single: My Happiness, another old Ink Spots hit; both sides reissued on the Complete 50's Masters box set; he cut it again in '57 for RCA

Cover of HARBOUR LIGHTS in 1954 - recorded during his first session with Scotty & Bill, released in '76
Cover of I LOVE YOU BECAUSE in 1954 - inspired by Eddie Fisher's version; after the fifth take, Elvis, Scotty & Bill started fooling around with That's All Right (see there)
Cover of MILK COW BLUES in 1954 - as Milkcow Blues Boogie, lyrically matching John Lee Wills version, but crediting Kokomo Arnold exclusively
Cover of THAT'S ALL RIGHT in 1954 - acting the fool as That's All Right Mama, immediately followed by Bill Black; recognised by Sam Phillips as the perfect synthesis of R&B, C&W, gospel and pop; less lyrics than Crudup
Cover of WHEN IT RAINS IT POURS in 1955 - as When It Rains It Really Pours for Sun, finally released in '65 with overdubbed instruments on RCA lp Elvis For Everyone; his original version was later heard on Elvis: A Legendary Performer Vol.4
Cover of DREAMING BLUES in 1956 - n°1 US as Heartbreak Hotel, earning him co-credits; Heartbreak Hotel was written bij Tommy Durden and Mae Boren Axton, inspired by an intriguing newspaper story about a serial holdupper with remorse, walking a lonely street since his baby left him; in his book about this song, Walk A Lonely Street (George Smith Publications - 2020) Tony Plews reveils the original articles and the name of the holdupper, shot dead by a liquor store owner in El Paso, TX; Tommy Durden came up with the first line (Well since my baby left me), Mae Boren Axton raised a Heartbreak Hotel at the end of that lonely street, delivering the rest of the song in 22 minutes flat; Tommy Durden introduced Heartbreak Hotel a few times live with his own band The Swingbillys, but they didn't like it too much and Elvis first started singing it live in december 1955, that's following James Dean's car crash and shortly after seeing Rebel Without A Cause
Cover of ARE YOU LONESOME TO-NIGHT in 1969 - the famous "laughing version"; triggered by his own wit, pills and a slightly out of key backing vocalist; inspired by the gentleman right in front of him at his International Hotel dinner table, El sang: "Do you gaze at your bald head and wish you had hair" instead of the standard "Do you gaze at your doorstep and picture me there"
