Our band did this the first few games at the Info 10 years ago. The first game was a sellout & it was a lot of fun having the band hop around to the different sections. The second game had 20K & it still worked well. But as attendance dwindled it became awkward for the band to pop up in a section & basically serenade 5 ppl. π
Hopefully, one day, attendance could get back to around 15K & I'll bet the band would start doing this again.
But you are right, it was GREAT when they were doing it the first couple games 10 years ago.
