In with the in crowd

Outside HMV in Glasgow:

Me: Could you tell me what you're all waiting for?
Young trendy woman: It's a singer. Doing a signing.
Me: Wow! Do you know which singer it is?
YTW (exchanging knowing glance with friend): Eh, yeah.
Me: So, would I know who it is?
YTW: (exchanging further knowing glance with friend) Eh, no.

End of conversation.
