You can now purchase Eric Idle's concert based on The Life of Brian — Not the Messiah — in many forms. Here's a link to order the DVD. Here's a link to order the Blu-ray. Here's a link to order the CD. Soon, I will probably be offering a link that will arrange for Eric to come to your home and sing this little number in your patio.
The CD, by the way, is actually a CD-R, meaning that when you order a copy, they make one up special. There is apparently no mass-distribution CD release so you probably won't find it in your local CD store. That is, assuming you even have a local CD store.
Here's Eric leading us in song. Five more repackagings of this and I'm going to start to feel about Monty Python the same way I'm starting to feel about Cirque du Soleil.
