Quicksilver Messenger Service
I'm listening to a TIDAL mix of their songs. Pride of Man is currently on. I hadn't started out listening to this. I had been listening to a Jeff Beck live album. Once that album was exhausted, TIDAL automatically began playing other songs, and the second or third one was QMS' songs.
Honest admission: I didn't know this group existed till today. Oh, I knew some of their songs, but not the name of the group.
