Phish performed Frank Zappa's 'Peaches En Regalia' during one of their New Year's Eve shows last December. All of the shows were made available as digital download, and also on CD (for the old folks).
I recently received my copy (and, yes, I was starting to get worried...) and it looks and sounds fabulous.
OK, so maybe it's not their best performance of 'Peaches' but they did play it.
A beautiful tribute.
And what a concert...
