My thoughts on this new show are very here and there. Let me see if I can try to organize in some format or another.
Firstly, I would like to mention that the park has produced many entertaining shows that do not follow the hamlet theme. Many of these shows mostly popular with the general public, but a few popular amongst the enthusiasts. Now, I personally prefer the show to fit the theme of the hamlet even if just obscurely, but if it is an entertaining show, it is entertaining.
Also, I do remember a few people saying Killarney Kommotion would have been a much better show indoors because it wouldn't clash with the village theme. Why not apply the same logic to this show? Why can't this show be almost irrelevant to England altogether as long as it is very well produced and set up indoors where it wouldn't clash with the theme outside?
The following is much more personal opinion rather than a general idea, I guess you'd call it? However, I honestly wouldn't mind a "British Invasion" type show as long as the show holds to that theme. If the show is going to be about the "British Invasion" it should have music selections and a story that follows that. I would be okay with that because I am sure they will pick good songs.
I also wouldn't mind a show that uses newer British songs or songs from British artists, but the show must stay within that realm. There is no need to mix 00's with 60's. The only show that I ever felt pulled this off was American Jukebox and Night Beats. Both had great song selections along with a somewhat loose story to follow if you desired or just enjoyed the music if you'd like.
If they do a "British Invasion" type show from what rumors dictate, I want it to be based very similarly like Night Beats. Something that takes you down the timeline, yet it still stays within the realms of "British Invasion".
Because the Globe is not also a dining area, I also would love to see some sort of story behind the show; however once again, there have been plenty of successful shows at the park that never had a story or had a weak story such as some of the Irish dance shows, Mix It Up, just to name a few.
BGW Family, I would also like to help ease you some. As far as your worries over the attendance over the concert with Bridgit Mendler I wouldn't be too worried except for concerts. All her attendance shows is how much people enjoy her, not her style of music, but her and her songs specifically.
I'd like to point out your concerns about the DJ as well. The park has contracted professional DJs before way in the past that have played top hits and current music, but the shows have not shown much in relation to that. In fact Killarney Kommotion is the only show I can think of that is primarily composed of hit current songs. Other than that other shows may have had one or two songs thrown in, but that is just one or two not half the show.
