Throughout this period, they had a steady stream of releases on RCA in
Mexico and one of these, a Mexican popular tune named "
María Elena" (
Lorenzo Barcelata; named after the wife of a Mexican president and recorded in 1958), became a steady seller, a success throughout Latin America and was finally released on a single in the
U.S. in 1963. It spent 14 weeks on the Hot 100 in the fall of 1963, four of which were in the top 10 in November 1963, reaching number 6, number 4 in
Canada, and had similar success in the
United Kingdom. It sold over one million copies, and was awarded a
gold disc. Los Indios Tabajaras continued touring throughout
the Americas and Europe, and in 1964 they had another two releases, "Always in My Heart" and "Marta." Although "Always in My Heart" made the
Billboard Hot 100, neither of these were nearly as successful as "Maria Elena." Their fluent guitar playing caught the ear of American guitarist
Chet Atkins and, along with pianist
Floyd Cramer, they recorded an
instrumental album in
Nashville,
Tennessee. They also recorded and released material with singer
Don Gibson, including a re-recording of Gibson's 1958 hit "
Oh Lonesome Me". ==Later years==
