Mars Williams, an American saxophone player known for his work as a member of the Waitresses and later the Psychedelic Furs, passed away at age 68, reported Variety. Williams died on Monday.

Williams` sax was a key element of the Waitresses during the group`s short but impactful two-album tenure in 1980-83, heard on the signature songs "Christmas Wrapping," "Square Pegs" and "I Know What Boys Like" as well as saxophone-heavy deep cuts like the title track of their "Bruiseology" LP.
