I don't suppose anyone has seen this since & knows if John Lithgow is back on yet? I talked my other half into coming along to see this one as he missed out on seeing Stories by Heart back in 2009. He'll be a bit gutted to miss out again!
I think along with the mobile phone reminder they should also remind people that they are not at home in front of their televisions!
At The Globe last week there was a couple in front of us that each had a giant cookie in seperate paper bags that they insisted on rustling loudly as they broke off bits off to eat.
An announcement along the lines of..."just because you rustle paper bags/sweet wrappers/crisp packets etc reeallllyy slowly doesn't make it any more quieter, it just prolongs the torment for audience memebers around you" might do it!!
I also unfollowed them a month or so ago because of all the live tweeting they do, it just filled my timeline up too much. It got a bit OTT...espcially when they would tweet live from a Q&A or something like that.
