Musical Careers that should have lasted

Of the singers/bands out there that were, at one point, well known and had a hit or two, but then their careers went down hill, which ones do you think should have stayed popular and should still be popular today? Which ones would you like to see make a comeback?
As for me, I’m sad that the Jeff Healy Group quit making hits by their third album.
I’m also sad that (yeah, go ahead, make fun of me :slight_smile: ) Def Leppard’s come back attempt only got them one hit (Promises), before they faded back into obscurity.
And finally, for now, until I can think of others, I wish that Queensryche was still big.
