The Chipmunks were very popular for the next few years; "Alvin's Harmonica" went to #3 in 1959, and the rodents got their on cartoon series - The Alvin Show
- which ran from 1961-1962. They had some success with a 1964 album of Beatles covers, but by the end of the decade, it seemed that fad had passed.
Seville died of a heart attack in 1972, and in 1979, his son Ross Bagdasarian Jr. assumed control of The Chipmunks, doing the voices of David Seville, Alvin, and Simon, while Ross Jr's wife Janice Klarman did the voice for Theodore. In 1983, they got another TV series, Alvin and the Chipmunks
, which ran until 1990. In the '00s, there was another Chipmunk resurgence, with a series of movies and some novelty cover songs that placed on the Hot 100 (their version of "Bad Day
" made #67; "Funkytown
" went to #86). In 2015 they got yet another TV series, this one called ALVINNN!!! and the Chipmunks
