Guillermo Alba

Tenor cómico active in zarzuela at the dawn of the 20th century in both Madrid and Barcelona. Other than that, I find him at the Teatro Principal in Cádiz in spring 1900 (he had been there before as he was already "well-known to this audience"), at the Teatro de Verano (an open-air season) in Alicante in June 1904 and at the Teatro Comico in Cádiz in February 1905.
