Is this afternoon by Nickelback an appropriate song for a school talent show?

It depends on the context and the specific school. While Nickelback is a popular rock band, "This Afternoon" is not one of their most famous or well-known songs. It is also a song about drinking and partying, which may not be appropriate for a school setting. Additionally, some people find Nickelback's music to be offensive or distasteful, which could make it a poor choice for a school talent show. Ultimately, the decision of whether or not to perform "This Afternoon" at a school talent show should be made by the school administration in consultation with the student performer.
