I like to sing along to show tunes. 
I love show tunes too!  I love going to musicals!
I do too! And I grew up watching the movies. What is your favorite musical?
There are so many great ones!  Kanky Boots is a fun one with music by Cyndi Lauper
I've never seen that one. I like some of the classics like The Sound of Music.
Yes The Sound of Music is amazing.  I watch that every time it comes on
I love how the show tunes/songs are actually part of the story. 
Yes.  While show tunes can vary greatly, they do usually fit the story and the context of what is going on.
Yes, it makes it very enjoyable. I like the recent one The Greatest Showman
I have not seen that one but I have read books about PT Barnum and his circus
