"I've Lost You" is a song written by Alan Blaikley and Ken Howard (under the pen name 'Steve Barlby') for Iain Matthews.
It was originally recorded by Mathews in 1969 and released on his first solo album after leaving Fairport Convention: Matthews' Southern Comfort.
As a newly released single, Presley included it in his setlist during his third Las Vegas season (August/September 1970) and the version from 12 August Dinner Show was included in the MGM movie Elvis: That's the Way It Is.
[6] It was also a top 10 hit in the United Kingdom where Presley's career was on something of a major resurgence, reaching number 9 for two weeks in November and December.
[7] The song might be seen as reflecting the state of Elvis' marriage to Priscilla at the time it was recorded (4 June 1970).
