Never Before...one more time now!

Before The Muppet Movie was unleashed upon cinemas, the Muppets themselves gathered in Coconut Grove, Hollywood, for a small, private party -- in other words, a huge celebrity bash hosted by Dick van Dyke and Rita Moreno, featuring a plethora guests ranging from Christopher Reeve and LeVar Burton to Vincent Price and Liberace. This was The Muppets Go Hollywood, a one-hour tv special which aired on CBS in 1979.

Within the program for this glamerous promo party, Johnny Mathis joined Rowlf at the piano to croon his rendition of Never Before, Never Again, as Kermit and Piggy gaze on from a nearby table-for-two.
