In contrast to Presley's lengthy and hugely successful career, both the Silhouettes and the Elegants reached number one in 1958 with the only singles of their respective careers to enter any of Billboards charts: both the former group's "Get a Job" and the latter's "Little Star" topped both R&B charts as well as the magazine's pop listings, but neither of the two doo-wop groups would ever chart again. Justis, Pérez Prado, and the Kalin Twins also reached number one in 1958 with their only R&B chart entries, although they did place other songs in the pop charts.
