Not all.
We recently saw Justin Heywood of the Moody Blues and he put on a great show with just two backup artists.
Also Peter Noone, “Herman” of Herman's Hermits, does a great live show, with a lot of funny mocking of his contemporary 60’s performers.
They are not all bad - the two above still had style, grace and self-respect.
Bowie pretty much dropped out of sight for ten years, which actually helped his legacy, and people were actually excited when he released his last two albums, whereas his releases in the 90s were pretty much met with indifference, even though, IMHO they had some of his best work.
“all the rock groups from the 60âs and 70âs are too. Whatever happened to style, grace and self-respect? “
Well, few from the 60’s and 70’s, much less the 80’s or 90’s, ever had it.
“There are exceptions like Leonard Cohen...”
And an exception he surely is. He’s gotten better with age, continually refreshing old and newer songs with OUTSTANDING musicians and backup chick singers. He’s got style, grace, and self respect in spades. His fans travel all over the world to see him in concert.
He’s the one artist, IMO, worth not only the price of a ticket, but plane fare and a hotel room too.
Check out some of his youtubes.
