Patterson withdrew from the limited engagement due to a scheduling conflict.
Sunnyside Up will play the East Side venue April 4 at 8 PM, April 5 at 3 and 8 PM and April 6 at 2 and 8 PM. Charles Osgood will host the concerts, which feature direction and choreography by Randy Skinner and musical direction by Vince Giordano and Joseph Thalken. Robert Kimball is artistic director.
In addition to Sikora, the evenings will also boast the talents of Vince Giordano & The Nighthawks, Nancy Anderson, Jeffry Denman, Jason Graae and Tony Award winner Randy Graff.
The show, according to press notes, "focuses on the megastar songwriting team of Prohibition-Era Tin Pan Alley who turned out hits like 'You're the Cream in My Coffee,' 'Button Up Your Overcoat,' 'The Best Things in Life Are Free' and the definitive college musical, Good News."
