A couple with David Bowie. I saw the first one with my parents.
Bowie and Bing Crosby - Peace On Earth / Little Drummer Boy
Then there's this one with Bowie and Annie Lennox joining Queen for Under Pressure!
I'm having flashbacks to when I was a DJ (1980-1983) which meant playing a lot of Disco, while simultaneously playing in a Rock band. Needless to say, I was smart enough to not mention my job duties to the other band members who were mostly of the "Disco Sucks!" variety. ?
Personally, I love a LOT of genres so I enjoyed both!
