I've watched a video of a Lightsleeper gig on YouTube and as much as I expected to be put off by the Finn family playing Crowded House songs, I actually quite enjoyed it. Liam brought a sense of youthfulness, humor, and energy to the songs that I haven't seen since the Paul Hester days. I also enjoyed the band's full on performance of "Black & White Boy". They were into rocking out in a way that Crowded House circa 2010 wasn't and I could certainly see myself enjoying more of that if Liam were to join CH. Elroy's drumming was fine too. Only Sharon seemed out of her depth on a song like "Pineapple Head," so I'm glad Nick is still around.
One thought I had was that maybe Mick Fleetwood would play drums on a new CH album and that Elroy might do drums on tour. That's what happened with some of the songs on Lightsleeper already. Not sure, but I think joining Crowded House as a drummer is probably not befitting of the stature of Mick Fleetwood.
