Nicky Byrne, Shane Filan, Cian Egan and Mark Feehily announced they were retiring Westlife in October 2011, but not before this final farewell tour. It proved to be an opportunity to roll out the red carpet for Facebook-status emoting and self-pity about entering the post-fame abyss. The endless video clips squeezed in throughout their two-hour set (no sign of Brian McFadden, who left in 2004) must surely have exhausted even the most devoted attendees at some point during the evening.

When these blazin’ psychedelic jazzers first landed here from Austin in 2007, there’d already been four or five years’ worth of herky-jerky cod-post-punk-reviving going on, way past the point of overdose, but White Denim were different, and obviously worth making an exception for.

There is a shouty lady outside the Theatre Royal in Brighton who takes strong objection to us attending tonight’s Brighton Festival performance of Matthew Herbert’s One Pig.  The show is based around the life and death of a pig, from birth to plate, and includes pork being cooked. We are, she tells us as we enter, “hypocritical vegetarians with the blood of farm animals” on our hands. Matthew Herbert is not a vegetarian but she has hit on a crux contradiction about the evening (albeit in the unfortunate manner of Crazy Cat Lady off The Simpsons).

There comes a point in almost every great soprano’s career when she tells the world that Tosca, the Marschallin or Isolde be damned: what she wanted to sing all along was The Great American Songbook. This announcement tends to be made - how shall I put this? - later rather than sooner. In Jessye Norman’s defence, in 1987, just five years after her landmark, ultra-luscious recording of Strauss’s Four Last Songs, she recorded a disc of Gershwin, Richard Rodgers et al.

The proto version of this tribute show took place at Queen Elizabeth Hall in 2008 on the eve of the 30^th anniversary of Sandy Denny’s death. This tour coincides with the release of a new box-set and draws on Thea Gilmore’s courageous recent settings of some of Denny’s rediscovered lyrics. A career-spanning set of covers, it pours water on the embers of a stunning back catalogue as much as it reignites them.

One image remains stuck from Watch the Throne's second of five sold-out nights in London; it’s a song-long vision of Kanye West and Jay-Z – aka J Hova or just Hov – sat side by side for Hov’s “Hard Knock Life”. Hov’s words fell out of his mouth seemingly effortlessly as the track's structure emerged while ‘Ye sat in a silent, contemplative stoop - his dripping sweat and jewellery making him look post-marathon mid-set.

“Post-classical” the FatCat label call it, and well they might. All three of the acts who played at the Barbican last night in one way or another used the instrumentation of the classical concert hall but in a way that was completely dislodged from tradition – not raging against it, nor fighting to escape it in the sense of high modernism, nor reviving it, but rather looking back on it as something other, something of a different era.

Often it can seem the sheer struggle of early reggae gets lost in all that happy, spliff-smoking Rastafarianism of Bob Marley's Legend. For one-time label-mate Jimmy Cliff, however, there was never any sense of “every little thing's going to be alright”. In the 1972 film The Harder They Come, he played a musician forced into crime and eventually shot by the police. And as a singer-songwriter, over a 50-year career, he has sung of injustice and hope. Last night, in front of a rambunctious indigO2, a 64-year-old Cliff showed he has absolutely no intention of mellowing.

Scissor Sisters’ breakout cover of Pink Floyd’s “Comfortably Numb” was so downright preposterous it looked likely to doom the New Yorkers to one-hit wonder status; it’s the kind of balls-out release that comes along only very infrequently. Thankfully for everyone, however, they’ve gone on to become one of our most treasured pop acts - headlining arena tours in the UK, enjoying life at the top of the charts and attracting fans from across the board.
