"Two actors from a real musical will be performing on a fake talk show which is part of a real soap opera.
Cheyenne Jackson and Jenn Gambatese from the Elvis-inspired musical "All Shook Up" will perform a song from the musical on Erica Kane's fictional talk show on the daytime drama 'All My Children'. "
The episode was announced as airing on September 14. However, if there were any pre-empted episodes due to coverage of the Katrina disaster in New Orleans, it would probably be pushed back a bit.
If you're that interested in seeing it, it might be wise to watch the show all week. Just to be sure you catch it........
