Trom agus Éadrom (English: Heavy and Light) was a bilingual television variety show which was broadcast in Ireland by Radio Telefís Éireann between 1975 and 1985. The show was presented by Liam Ó Murchú and, in spite of the bilingual aspect of the programme, was one of the more popular shows on Irish television. Liam became a household name and was famous for his catchphrase "bualadh bos" (English: "clap hands").
