Is staff plural?
It always sounds wrong to me when people refer to a proper team, group, band, etc. in plural form, e.g.:
Nirvana are the creators of grunge. The Avalanche are on the road to the Stanley Cup this year.
To me, this sounds correct:
Nirvana is the creator of grunge.
If the name is plural, it sounds correct:
The Foo Fighters are on tour this year.
What is the rule for this? I seem to be hearing this more and more these days.
