"I'm Yours" is 1961 song written by Don Robertson and Hal Blair.
The song was recorded by Elvis Presley on June 26, 1961, at RCA's Nashville studios, and released on the album, "Pot Luck with Elvis", on June 5, 1962.
It was not released as a single until three years later when it was featured in Presley's 1965 film "Tickle Me".
"I'm Yours" peaked, on the "Billboard" Hot 100 , at number 11 in October 1965.
"I'm Yours" reached the top of the "Billboard" Easy Listening chart to become Presley's third consecutive number-one single on the chart. 
Both the Rimes and the Yearwood versions debuted on the U.S. "Billboard" Hot 100 on the week ending June 14, 1997.
LeAnn Rimes' version peaked at number two and spent a record-breaking 69 weeks on the chart, more than any other song in history until Jason Mraz's "I'm Yours" in 2009.
It also spent 32 weeks in the U.S. Top 10, 62 weeks in the U.S. Top 40 and 34 weeks on the UK singles chart.
Trisha Yearwood's version was moving quickly up the charts, getting as high as number 23, when MCA refused to issue any more copies of the single, for fear of cannibalizing album sales.
The limited press run of 300,000 sold out quickly, and the single was off the Hot 100 after 12 weeks.
Yearwood's single on the country charts quickly climbed all the way to number 2.
Rimes' version ranked at number 4 on Billboard's All Time Top 100 in 2008.

On the Billboard Hot Adult Top 40 Tracks chart the song was number one for a total of nine weeks.
The single later received Mainstream Top 40 airplay, eventually topping that chart as well.
Due to its gradually building crossover appeal, the song has had extremely unusual longevity, not reaching number one on the Mainstream Top 40 until December 2008, ten months after its release and seven months after it debuted on the VH1 Top 20 Video Countdown.
In fact, VH1 had already retired the song in early October, 2008 after a 20-week run.

A year into its release, it topped another chart for the first time, when it hit number one on the "Billboard" Hot Adult Contemporary Tracks during the week of February 5, 2009.
This marked 11 months since the song had topped its first chart in the U.S., when it reached number one on the Triple A chart in March 2008.
"I'm Yours" spent 16 weeks at number one on the Adult Contemporary chart.
In addition, after topping the Adult Contemporary chart, "I'm Yours" became the first song to top the Triple A, Adult Top 40, Mainstream Top 40, and Adult Contemporary charts.

"I'm Yours" made its debut on the British singles chart on December 12, 2008, at number 78 and then slowly climbed up the chart until it peaked at number 11.
It spent the whole of 2009 on the chart apart from the final two weeks of the year, then re-entered in January 2010 and again in August, and has now clocked up 56 weeks on the official UK Top 75, making it currently the 15th longest runner of all time and "the" longest never to make the Top 10, and 84 weeks on the Top 100.
