what year did Bridgemen do Piachi? 80???

I remember them doing Circus Circus in 80 and it makes sense that they would
have done Piachi that year, but I just wanted to see if anyone knows for
sure. I will never forget the drum major that dropped down into the full
straddle split on the DM podium. Having been involved in both karate and
dance since age 18 I now what it takes to work up to that kind of
flexibility, just incredible!!!
