"Whereas PB is a big fish in any pond"
This is entirely a matter of personal taste - as reflected by Peter's empty appointment diary - not a problem with any of the others mentioned to my knowledge.
It is possibly to have respect for Peter's character without particularly liking his singing, which reflects my own attitude.
Let's leave the beatification to the church and avoid contentious arguments on a thread paying rightful respect to somebody who deserves it, shall we?
