Then I recommend that you have a look at this old version of Joseph and the Amazing Technicolor Dreamcoat:
The person who uploaded these didn’t upload the full show, but it shouldn’t be very difficult to find the rest elsewhere on the net. In fact, the official Joseph site (listed below) has the DVD of the full performance for sale.
I went to see Joseph a few times as a child, and have fond memories of going to the Shawnee Playhouse with my mother, aunt and cousins- I remember singing on the way back home late at night, and generally having a wonderful time.
