The funniest thing I remember about Christopher Cross was when SCTV did a bit on how Michael McDonald used to sing backup on like every song back then, so it would show him running from studio to studio just in time for him to sing his “Such a Long Way To Goooooo...” line in “Ride Like the Wind.....”
It's like Linda Ronstadt singing backup on half the country and rock albums from the 1970s and 1980s.
