4 questions re this file..

[Peter Teeson]

Hi:
I'm still a newbie and have searched the Learning, Glossary, & Notation but 
cannot find the answers.
Because my eyesight is not so good anymore ( I'm in my '70s) I want to take 
some of the lead sheets I have and make them larger.
Below is the one I am working on and there are 4 questions:

1. I want to make this large but global staff size is set to 23 which I believe 
is the max
2. I want to only have 2 bars per line
3. I don't understand why there is a bar check in the lyrics at 1/8
4. why are there missing hyphens. I put them in the lyrics.

TIA for your help…

Peter
