Question 12

What is the link between these 11 answers? I’m looking for three specific things, but I won’t be too particular about the one that involves a two-digit number.

*mononymous* *solo artists* with *Top Ten Billboard hits*. (“Laugh At Me” was credited to “Sonny” rather than “Sonny & Cher” or “Sonny Bono”.)
