The first 3 rows in 111 sing for sure, can't comment on the rest. I've lost my voice many at time.
While I can't speak for row 4, those of us in S111 Row 5 take exception to that generalization ---we sing and cheer along heartily for a full 90 or more
(Except when ChrisFizik looses his place or forgets the words to the ineeb's songs and throws us all off )
