Maybe a little on the extreme side, but the idea is the same. DD did one album with Stevens about 5 yrs ago. Since then, there have been 3 studio and one live album with Corabi.
Imagine a Rush fan around the time of A Farewell to Kings still talking about how great that first album was and wishing Rutsey would come back.
It's different than, for example, someone wanting Roth back in Van Hal
