In my opinion, Bat should never be omitted, ever! Aside of it being in my top 10 favourite songs of all time, it's kinda the Meat Staple. Maybe the more commonly heard songs become a little bit repetitive for people who know Meat's music well and go to a lot of shows, but EVERYONE knows Bat, and I think people who know his music less well have to be catered for too in terms of including some of the more well known stuff.
As for Frying Pan, the pyrotechnics for that song broke my camera (twice) (with the heat) so I vote for keeping this song but toning down the fire or someone providing a heat-proof box for my camera
(and I'm obsessed with taking photographs of just about anything I can, so leaving the camera at home is not an option
[and yes I do accept it's a limitation of the camera if it can't take pictures of flames!])
I rather like the other songs you mentioned too however I would accept that I can't have a show with every single Meat Loaf track I like because the gig would last a day or so! There isn't a single Meat song that I have yet tired of hearing and I don't expect to, however I know there are a lot of people here who have more years listening to Meat's music than I do (not that I am saying I expect them to have tired of it either!).
