It's still interesting how Jesse's parents never ended coming on after the Wedding, even on special occasions. It would probably be strange to see them there after so long, although if they had made appearances in between it wouldn't really matter.
I don't mind the idea of the name mixup, and instead of having a popular alternative rock band you have three elderly ladies. Generally I'm not a big fan of the performing episodes in general, so whatever they decided on likely wouldn't make too much of a difference to me personally.
