[1] Plant and Alison Krauss later recorded a version of the song for their collaboration album Raising Sand released in October 2007.
[3] Plant explained that "Please Read the Letter" is a song about yearning for someone, adding that the lyrics are about "unfinished business".
Plant and Krauss' version of the song initially failed to chart, but after winning the Grammy Award for Record of the Year, the song entered the Billboard Bubbling Under Hot 100 chart at #20 (the virtual equivalent to #120 on the Hot 100) in 2009.
Chris Jones, in his review for the BBC, felt that the version by Plant and Krauss is "completely improved" from the original track.
[6] Thom Jurek wrote for Allmusic: "Slow, plodding, almost crawling, Krauss' harmony vocal takes it to the next step, adds the kind of lonesome depth that makes this a song whispered under a starless sky rather than just another lost love song.
