The song is a country ballad that begins with the female narrator noticing her phone ringing, and refusing to answer it because she recognizes the number. The woman is aware that the male character is most likely in a bar and drinking alcohol. Therefore, she refuses to answer her phone because she knows that she is always his "last call". This is a play on the bartending term "last call", which refers to the last round of alcohol served before the bar closes for the night.
Critical reception
"Last Call" was well received by critics, being met with several positive reviews and was nominated for two awards. Allmusic reviewer Thom Jurek called the song " a classic example of what makes Womack such a fascinating and emotionally resonant singer." Country Universe gave it an A rating, and considered that "Last Call" was reminiscent of her 2005 hit, "I May Hate Myself in the Morning". The song received a "thumbs up" review from Engine 145 reviewer Brady Vercher, who also compared the song to "I May Hate Myself in the Morning" and said that "although the lyric doesn't accentuate the emotional conflict, Womack's vocal dips with indecision as she delivers a splendid performance." This song was number 52 on Rolling Stones list of the 100 Best Songs of 2008. Editors at Billboard wrote, "Haunting single “Last Call” is song-of-the-year material on a number of levels: songwriting, vocal performance and production." Chuck Arnold of People Magazine listed the song as a hot download and wrote, "Lee Ann Womack will have you busting out the hankies with the touching breakup ballad "Last Call." In December 2008, the song received a Grammy award nomination for Best Female Country Vocal Performance. "Last Call" also received a nomination for Female Video of the Year in the 2009 CMT Music Awards.
