"Imbelli does not share the left's attitude towards liturgy."

"The Left" has an attitude about liturgy? Really? That's news to me. When it comes to politics I am rather liberal and so can generally be considered part of "The Left." But when it comes to worshiping God, while I am no fan of Tridentine ritual complete with berettas and lace, I do like things to be done well, but in a straightforward manner. Does that make me part of "The Right?" I don't think so, which make me rather suspicious of over-arching statements like this one.

As for singing different words to well-known hymn tunes, I have no problem with that. With certain notable exceptions in which texts and tunes are strongly wedded to each other, hymn tunes can be sung to any text that shares the same meter. That's the way metrical hymnody works. Singing new words to old tunes can be helpful since the tune is already familiar, which makes things easier on the congregation. Isn't that a good thing?
