The way to enhance the Anthem experience is to have someone on the red carpet singing it. This has the effect of motivating people to join in. Singers are out there to do this. The Devils could hold a completion to find a singer for their anthem? Rhythm did a great job of this. Most NHL teams have a resident singer so could be a promotion exercise, a bit like the mascot one.
Alternatively you approach the music colleagues, societies etc, with the carrot dangler being free tickets for the singer and friends. This might also encourage more paying customers from the college/societies you approach to attend. This is a logistical exercise getting someone every week to do this, and not sure of the resource implication for the Devils in organising this, but it will add the match night experience more than recorded versions. The band last week for example could maybe have been approached to do an acoustic version if they were able.
