I read this yesterday regarding Steely Dan touring in 2018. Similarly, a founding member (Walter Becker) died.

In a September installment of Rolling Stone's Music Now podcast, Fagen admitted he would "would actually prefer to call [the group] Donald Fagen and the Steely Dan Band or something like that." He added, "We got a lot of flak from Live Nation about [not] calling it Steely Dan … To me, Steely Dan was just me and Walter."

I'm sure similar forces were at play to keep the Henley/Schmit/Walsh group that is touring now named "Eagles."
