Ryan Cayabyab (born Raymundo Cipriano Pujante Cayabyab but affectionately known as Mr. C) is a renowned Filipino musician and was the Executive and Artistic Director of the defunct San Miguel Foundation for the Performing Arts. He was also a resident judge for the only season of Philippine Idol in 2006.
His works range from commissioned full-length ballets, theater musicals, choral pieces, a Mass set to unaccompanied chorus, and orchestral pieces, to commercial recordings of popular music, film scores and television specials.
Cayayab's current project includes the Ryan Cayabyab Singers (RCS), a group of seven young adult singers comparable to his prior group Smokey Mountain in the early '90s. After FreemantleMedia decided not to renew the Philippine Idol franchise, Cayabyab transferred to rival show Pinoy Dream Academy (season 2), replacing Jim Paredes as the show's headmaster. PDA 2 started on June 14, 2008.
Ryan, Ryan, Musikahan, the television show, has won a total of fourteen awards as Best Television Musical Show and for Mr. Cayabyab, the Best Show Host in various television award-giving bodies. Likewise, as an artist, producer, arranger, and composer, he has won a total of eighteen awards from the recording industry for various commercial recordings. He has produced albums of the popular Filipino teen group Smokey Mountain, Broadway and West End's diva, Lea Salonga, and Spain's internationally-acclaimed singer Julio Iglesias.
In 2006, Cayabyab signed on as a resident judge for the first season of Philippine Idol, offering critiques for the contestants on the reality-talent show. He was said to be personally chosen by the top guns of Philippine Idol, while the other two judges, Pilita Corrales and Francis Magalona, had to undergo auditions.
