Have they permanently gone out of fashion?

If you had just 24 hours to spend in Italy, anywhere in Italy but limited to a 50 kilometer area, where would you go?
I'm taking suggestions for appropriate responses for the category of
Worst Primary Lead Singer Addition/Replacement in Rock and Roll History
It could be a required or optional change, but it has to occur to a band AFTER they have released their first album. There are so many candidates to choose from, but list the band AND the singer, since some bands have had more than one primary lead singer change in their history. For examples, write
Van Halen, with Sammy Hagar
not just Journey, or Mickey Thomas. Give band and singer of poor choice.
After about a week of comment suggestions I'll create the poll.
