In the spring of 1967, Freddy Rizo-Patrón left "Los Hang Ten's" to create another band, a super-group, (
Traffic Sound). He contacted Sanguinetti to sing lead, as well as dovetailed his efforts with those made simultaneously by the members of two other bands, namely lead guitarist Guillermo (Willito) Barclay Ricketts, bass man Guillermo (Willy) Thorne Valega (Lima, 1950–2019), drummer Luis (Lucho) Nevares and, sax player
Jean Pierre Magnet, their combined efforts, thus leading to the final creation of
Traffic Sound. In the meantime, the "Los Hang Ten's" line-up was immediately re-arranged, as original 2nd rhythm guitar player de Orbegoso switched to lead guitar, thus replacing José Rizo-Patron, who also chose not to continue, opting instead to dedicate his time fully to his university studies. At the same time, another schoolmate, Jaime Sabal Saba (b. Lima, 1951) was added to play bass while a former child schoolmate, – who by then was attending another high school, Juan Geronimo de Aliaga Fernandini (b. Lima, 1951), the direct descendant of Spanish Conquistador
Geronimo de Aliaga, was then promptly recruited to play the 1st rhythm guitar position left vacant by Freddy Rizo Patron once he joined "Traffic Sound". Then in mid-1967, drummer García-Sayán recruited a close friend, the then future United Nations official and Nicaraguan Ambassador to Brazil and Perú,
Guillermo F. Pérez-Argüello, (b. Lima, 1950), to join the band and sing additional songs, mostly R&B and early Rock and Roll classics. Pérez-Argüello is the nephew, on his father's side, of the fifth Secretary General of the United Nations,
Javier Pérez de Cuéllar (b.Lima, 1920–2020), as well as the great-grandson, on his mother's side, of the 1959 Woman of the Americas, Dame
Angélica Balladares Montealegre (1872–1973), herself the aunt of actresses
Madeleine Stowe and
Felicia Montealegre, the latter the Costa Rican-born wife of US music composer and conductor
Leonard Bernstein. One of Pérez-Argüello's school mates while attending a boarding school in Chosica, a town located an hour from Lima,
Jesús Emmanuel Arturo Acha Martinez, a then 14-year-old high school senior of Argentinian and Spanish extraction who was the week-end guest of the Spanish businessman Tomas Datorre Compes, in turn a neighbor of the Garcia Sayan's family estate, attended in late 1967 at least one of their practice runs, Until about February 1968, "Los Hang Ten's" continued playing, mostly at week-end festivals and ad hoc venues but, with their college and university education just around the corner, they all parted along different ways, some taking up higher studies in North America and Europe, as was the cases for both Garcia-Sayan and Pérez-Argüello, the former taking a year abroad at the
University of Texas at Austin during his sophomore year of Law studies at the
Pontifical Catholic University of Peru, the latter obtaining high school, university, and post graduate degrees at
Miami Military Academy, in Miami, FL., the
College of the Holy Cross, in Worcester, MA. and later at
St Peter's College, Oxford, in the United Kingdom, the latter in conjunction with his post graduate Diplomatic Studies at
the University of Oxford. While the remaining band members all attended Peruvian universities, one of them in particular, Juan Geronimo de Aliaga, stayed the course for the next two years, eventually playing rhythm guitar for The Beatnicks, a rock ensemble fronted by Andres and Ramon Carrillo Valdes, the latter a future Peruvian and UN diplomat who is currently the Director of the
Nebrija University Foundation in Madrid, Spain. To this date, several of them remain very close as friends and, on occasion, still jam together. ==References==
