I think the expression we'd be looking for is "mixed response". CMU's man at the gig sent in this report: "Little more than a drunken pub singer. Real car crash stuff and so very sad...necking back the drinks, totally pissed, incoherent most of the time, dropped the mic, tears, real vacant moments. Too painful to watch in the end". Yeah, mixed.
Amy Winehouse was booed last night at the first night of her UK tour in Birmingham. She delivered a pretty shambolic set by all accounts, and garnered some boos when dedicating a song to her slightly dodgy husband Blake Fielder-Civil (some reports suggest she changed quite a few lyrics in order to name check 'Blakey' too). Later on she responded to further booing by telling the crowd: "To them people booing, wait 'til my husband gets out of incarceration. And I mean that". During an encore she stopped singing midway through a song and walked off stage.
Winehouse, of course, cancelled a number of gigs earlier in the year because of "ill health". Some friends have expressed new concern for the singer after husband Fielder-Civil was arrested and jailed last week amid perverting the course of justice charges.
