It's been 10 years since Elvis Presley reached the country songs chart, and now the King has not one, but two songs in the weekly survey.

'Blue Christmas,' Presley's posthumous duet with Martina McBride, entered Billboard's Hot Country Songs chart at No. 43 this past week, following the No. 60 debut of 'I'll Be Home for Christmas,' with Carrie Underwood. Both tracks are taken from Presley's 2008 compilation, 'Christmas Duets.'

'Blue Christmas' marks Presley's 68th hit on the country chart. It's also the first time in his 53-year chart career that he's had songs debut in two consecutive weeks.

Although Presley first recorded his solo version of 'Blue Christmas' in 1957, it didn't reach the country chart until January 1998, when it peaked at No. 55.

'Blue Christmas' has been recorded by hundreds of artists in all genres of music, and has reached the country chart four times in its nearly 60-year history. The original version by Ernest Tubb peaked at No. 2 in 1949, while Vince Gill took it to No. 74 in January 1999, and Clay Walker reached No. 51 in January 2001. That makes the Presley/McBride duet the highest-charting version of the song since Tubb's original.

During his lifetime, Elvis Presley never recorded duets with other artists.
