Ok, so I was watching Broadway: the American Musical last night for the 4th or so time.

And I noticed something I thought was weird. They were talking about 42 street and then Cats and said that 42 street opened in 1980 and ran for 8 years at the Winter Garden theatre. Ok. Then they said that the next show to occupy the Winter Gardent theatre was the longest running show on Broadway- Cats. It ran for 18 years, right. Ok so a little math. 1980+8=1988 1988+18=2006? Somehow, this doesn't make sense to me. That Cats closed in 2006. Lol. Could someone help me out? Thanks!
