This Blues boogie is one of several tracks on Privateering to feature the harmonica playing of Kim Wilson of the Blues rockers The Fabulous Thunderbirds. "One of the most important things about the blues to me has always been the harp," said Knopfler. "Seeing Muddy Waters as a kid made a big impression on me, the harp was burbling away all the time, the band was swinging. And to me the greatest modern exponent is Kim Wilson, he's been my top man for many years, so it was really great to have him on board. We hit it off straight away and got a great session going."
Stephens Stills played timbales on the Bee Gees hit, "You Should Be Dancing." He was in the next door studio laying down a Crosby, Stills and Nash album and could hear Saturday Night Fever being recorded. Stills recognized its potential to be a monster hit and he wanted to contribute.
The lyrics for "Mary, Did You Know?" were written by Christian singer and comedian Mark Lowry, after his pastor asked him to write a Christmas musical for their church. Southern gospel musician Buddy Greene later added music to his words.
