The last fancy ice show I went to had a fair number of boys represented.
First, the guest skater was male, he did two solo numbers, but also randomly joined in on the "Lady Gaga" number- because who can resist that.
Then, we had two pairs teams (low level, and junior), the junior man also skated a solo, and in a few of the higher level group numbers.
Then, in the group numbers there were two other elite level men, one of whom is technically an adult, though he's been with the club since he was a kid.
And in the LTS group it seemed to be about 1/3 children.
As for adults, there was an adult ice dance number. This was mostly LTS level adult skaters, but also two college students who skated as children (since it was a "social dance" sort of thing, they nearly lapped one couple...) and an adult Gold male. Then a coach did a Sonia Henie style number following the ice dance (which was themed to her time period), so that's technically an adult.
The Adult Gold male also had a feature number, but not a solo.
The last low budget club show I saw (I was in) had about 1/4 of the LTS students who were boys.
Had 3 mid-level boys who did solos, group numbers, and duets (not pairs).
Had no adult men, but 2 adults - one a 'grandmother', one a younger adult (me, almost 30).
We don't have hockey kids participating in these shows.
