We really hoped that the Internet meme known as Rebecca Black and her musical celebration of the beginning of the weekend, “Friday”, wouldn’t stick around for another week. And although the novelty song has been slipping down the iTunes charts (it fell from #21 to its current position at #46), the Jonas Brothers are helping this tune outlast its welcome in pop culture. Nick Jonas (playing with his bros Kevin and Joe) covered Rebecca’s tune at the Concert For Hope in Los Angeles last night — and the whole audience chimed in to sing along. Live vid below.
