It is HIGHLY unlikely that you will see Lane after the first preview of the Frogs...notes will probably take awhile and there are a lot of things going on after a first preview performance.
Additionally, he isn't a real 'stage door' person. He will come out when he can and when he feels up to it, but is very shy and doesn't like meeting the public very often. IF you are lucky enough to see him, don't get in his face and gush or you are likely to get your nose bitten off!
