Oh definitely there were people who tuned in just to see Andrea, just like there are people who went to the show in Toronto just to see Andrea. The crowd turnout was rather higher than it has been at most recent pro skating events that I've attended. And Andrea's people have been pushing his appearance on this show (along with a number of other concerts and appearances he's doing this month). I even had someone from Universal Music sending me a press release about his album and the show because they're trying to reach the widest audience possible.
And in the past, when Michael Bolton was the guest star, I saw posts on the Michael Bolton message boards about his appearance on Gotta Skate, etc. When Ed Robertson from the Barenaked Ladies was on, I even was providing information for a BNL site on his appearance...
Make no mistake - they're not just targetting skating fans with these shows. I think the idea is to draw a broader audience by mixing the singers and skaters. Fans of the singer who would never have watched skating otherwise. Fans of the skaters who might not be aware of the singer before, or not aware that the singer has a new album coming out....And if you were a fan of Andrea Bocelli, not skating, wouldn't you want to see his face more than those distracting skaters on the ice? =)
