'll bet if he really wanted to, he could sing almost exactly like he did back in Live Aid, just that he's been using a different singing style for a while now.
I agree about the change in style, definitely. I just don't think B can project his voice, now, as strongly as he did 20 years ago, for any prolonged period of time without straining fairly badly. Sure, he might be able to get a large fraction of his original vocal energy here and there, but for an entire show, or series of shows? No can do. Sorry.
Sunday Bloody Sunday, sung then and now... I Will Follow.... the end of All I Want is You... New Years' Day... Desire... nope. They're all great songs, and I reckon Bono still sounds great when he sings them. The 'wiiiiiiiiiiild' bit towards the end of Wild Honey, compared to the 'whoooooooh's in With or Without You?
There's not the same vigour as there was 15/20 years ago, which is hardly surprising really.
This next comment is related, so bear with me: my dad was a very gifted, classically trained singer and he had an incredibly clear, sharp tenor. By the time he was in his mid 50's, he could still sing - but he sounded totally different, he couldn't hold those notes like he used to, and there was much less force in his voice. That's what tends to happen. I know everybody is different, but I do think the same thing has happened to our friend B.
Based on how he sounds both in the studio and live, these days, I don't think he could sing like that anymore - certainly not like he did in the '80s or early '90s.
I'm
not saying that Bono isn't still a great singer. One of my favourite U2 songs is In A Little While - warm, woody, gravelly, the sound of too many late nights and too much overindulgence over too many years... which makes the song what it is. It wouldn't sound right any other way.
I also adore The Ground Beneath Her Feet - I think that song is a great example of how much emotion Bono can muster, without being whiney... something that I don't think applies to many bands as well as it does to U2.
