Viegas is a
tiatr artist initially known for his work as a
child performer and later as a singer. On 8 December 1958, at the age of 9, he embarked on his professional stage career as a child artist in the
theatrical production Tuka Lagon (Because of You), under the direction and writing of Mog Joaquim. The subsequent year, in 1959, Viegas took on an acting role in another
tiatr named
Gharachi Durdoxea, which was also crafted and directed by Joaquim. In 1960, Viegas participated in a theatrical production organized by Isdorio Cruz who hailed from
Varca,
Goa. The following year, 1961, Viegas faced a personal loss when his father was
fatally shot, prompting his family to move to
Bombay. Despite this upheaval, Viegas pursued his education in Bombay. During his time in Bombay, Viegas caught the attention of a family friend named Carlos when he was singing
Konkani songs from
Goan tiatrs. Carlos then connected Viegas with the well-known
tiatrist C. Alvares. Impressed by Viegas'
solo vocal abilities Alvares said to him "You are perfect match to sing on professional stage", and cast him in two of his own productions in 1962-
Bhattam Anim Bessam penned by
Kid Boxer and helmed by Alvares. and
Patki Nhoim Ghatki (Not a Sinner, a Traitor). By 1963, Viegas had gained recognition on the
Konkani tiatr stage under the
moniker Master Osvi Viegas. During that year,
Anthony Mendes, then a leading
tiatrist, formally invited Alvares to cast Viegas in a role for his theatrical performance named
Goemkar Te Goemkar (Goans are Goans). The
tiatr production
Goemkar te Goemkar was a significant milestone in the career of Viegas. This
tiatr garnered attention and featured three separate performances over the course of three consecutive days. Throughout the shows, Viegas exhibited his
musical range by presenting three unique songs. One of Viegas's musical offerings, a piece rooted in the regional
Kunbi style, was particularly well received by the audience. The response from the crowd led Viegas to
encore the song, performing it a second time in response to the audience's demands. The positive reception of Viegas's performance did not go unnoticed. The popular vocalist Luciano Dias expressed admiration for Viegas's abilities and authored commendatory
critiques of the
tiatr in the
Konkani language periodicals
Cine Times and
Goa Times, both then-leading publications in circulation within
Goa. This coverage ultimately reached Viegas's mother, who resided in the region. Concerned about her son's involvement in the
Bombay (now Mumbai) theater scene, Viegas's mother took action, requiring him to retum to Goa. In order to cultivate discipline, she decided to enroll him in a
boarding school located in
Pilar, Goa. However, Viegas's passion for the
performing arts could not be extinguished, and he continued his involvement in school-based singing and drama activities with the guidance of school authorities, including the principal, Fr. P. Nazareth,
Bro. Peter Cardozo, and Alex D'Souza, who later pursued careers in
priesthood and music, respectively. Throughout his career, Viegas also toured extensively, performing Konkani
tiatrs in various
Gulf countries and European nations. ==Personal life==
