"Para Vigo me voy", known in English as "Say Si Si", is a popular song written in 1935 by Cuban composer Ernesto Lecuona with lyrics by Francia Luban (original Spanish version) and Al Stillman (translated English version). Early bands to record the song include Xavier Cugat's orchestra (1935) and Lecuona Cuban Boys (1937). The song was copyrighted in the United States in 1940. It became a hit in the US when it was recorded by The Andrews Sisters and Glenn Miller in 1940, and The Mills Brothers in 1953.

Releases including "Para Vigo me voy" often label the song as a "conga", or occasionally a "rumba". Thus, it is considered an early example of a "salon conga" or "ballroom conga", in the same vein as the famous "ballroom rumbas" such as "The Peanut Vendor" ("El manisero"). According to musicologist Alberto Pérez Perazzo, "Para Vigo me voy" is one of the first popular songs with a true conga rhythm.

One of the earliest recordings of "Para Vigo me voy" was made by Xavier Cugat and his orchestra featuring vocalist Desi Arnaz in December 1935 for Victor. Cugat re-recorded the song in 1945. In 1937, Lecuona Cuban Boys, the ballroom rhumba band established by Ernesto Lecuona himself, recorded the song for Columbia with a 1936 recording of "Patica y Mondonguito" as the B-side.

Popular American artists who have recorded the song include The Andrews Sisters, Glenn Miller and his orchestra, and The Mills Brothers. Besides, the song appeared in various films including It Comes Up Love (sung by Gloria Jean and The Guadalajara Trio, accompanied by Leon Belasco and his orchestra).
