"Old Habits Die Hard" is a song from the 2004 movie Alfie, with music by David Stewart and lyrics by Mick Jagger, and performed by Mick Jagger. It won the 2005 Golden Globe Award for Best Original Song. However, the song failed to get nominated for the Academy Award for Best Original Song, making it the first in five consecutive years where the song won the Golden Globe, but failed to get nominated for an Oscar. It was followed by " A Love That Will Never Grow Old" from Brokeback Mountain (2005), " The Song of the Heart" from Happy Feet (2006), " Guaranteed" from Into the Wild (2007), and the title theme from The Wrestler (2008).
Two versions of "Old Habits Die Hard" are available in the Alfie Original Soundtrack: One performed by Mick Jagger alone, and second version featuring Sheryl Crow.
