Steely Dan
Is this a person?
No, Steely Dan is a musical group formed in 1971 by two core members (neither named “Dan”; one of them died in 2017) and a rotating roster of supporting musicians. Over 100 different musicians have been part of the studio or tour lineups at one point or another.
The band is named after a mythical sex toy from a 1950s novel.
Why I Looked It Up
A friend had me listen to an album. I had known of their existence for decades, but couldn’t name any of their songs. I kept thinking it was a person (I’ve had the same problem with Pink Floyd and Fleetwood Mac, over the years).
