If they're playing two songs, then I guess it will be a Nicks song and a Christine McVie song. What will be interesting is when they do full concerts. I just hope that there won't be malcontents in the audience.
It will be interesting as you stated and I missed– the ticket purchasing public may be the most vocal about how they feel about Crowded House guy. If they truly value what they are paying the prized rate for, they may as well be receptive to Mr. Finn's charms.
