Gaslight is sick
The NHL almost always misses with musical performances and this is another bad one. What age demographic are they pleasing with this? 45+ at least? A modern New Jersey band like Gaslight Anthem would seem to be perfect for this type of thing, i can't imagine their fee would be on par with Cee-loo Green if not less.
Half the guys in the band are Devils fans and half are Rangers fans, they even made custom devils/rangers t-shirts during that playoff run a few years back. Missed opportunity!
