Danny Guillen

Danny Guillen is a Mexican singer whose song "Un Solo Corazón" became widely known in the 1980s. The track has remained familiar to listeners of Latin music for decades, though details about his career beyond that single are sparse.

He formed a band called Danny Guillen y su Grupo, which initially played in the ranchera style. Their sound reportedly incorporated other influences over time, but the group's recordings and touring history aren't well documented in available sources.

Some accounts mention controversies in the early 1990s involving allegations about the band, though these stories lack clear verification. What remains concrete is that "Un Solo Corazón" continues to surface in Latin music collections, keeping Guillen's name attached to that particular song.
