Paul McCartney enlisted Eagles star Joe Walsh to fill in with some nice classical guitar for a performance of his current single 'My Valentine' on tonight's 2012 Grammy Awards show.

As you probably know from news reports and album reviews such as our own, McCartney's new album 'Kisses on the Bottom' finds the Beatles legend performing traditional versions of the pop standards he loved as a child. 'My Valentine' is one of two original compositions on the record, but as you could expect, he's able to make it sound classic right away.

Walsh, as expected, totally nailed the vibe of the song with his performance, and McCartney turned what could have been a dusty library exhibit into a faithful and surprisingly lively trip down memory lane.

McCartney kicked off the night by winning an award for Best Historical Album for last year's re-issue of his 1973 album 'Band on the Run,' and would soon end it by leading an all-star 'Abbey Road' medley performance.
