I'm not sure that the American public has bought the hype around new Brit hopes the Vaccines, but late night talk show music bookers certainly have, as the group has hit a late night show for another performance of "If You Wanna." Last night they hit Kimmel's program wearing Lakers jackets and their own T-shirt (don't be that guy), and rocking sweetly. I was pretty thoroughly unimpressed when I saw the group at SXSW, and this performance does nothing to change that. Sorry NME.
