Calon Lân (Oh Pure Heart) Nid wy'n gofyn bywyd moethus Aur y byd na'i berlau mân Gofyn rwyf am calon hapus Calon onest, calon lân. Cytgan: Calon lân yn llawn daioni Tecach yw na'r lili dlos Does ond calon lân all ganu Canu'r dydd a chanu'r nos.

Cytgan: Hwyr a bore fy nymuniad Esgyn ar adenydd cân Ar i Dduw, er mwyn fy Ngheidwad Roddi imi galon lân. Cytgan: English I ask not for ease and riches Nor earth's jewels for my part But I have the best of wishes For a pure and honest heart. Chorus: Oh, pure heart so true and tender Fairer than the lilies white The pure heart alone can render Songs of joy both day and night. Should I cherish earthly treasure It would fly on speedy wings The pure heart a plenteous measure Of true pleasure daily brings. Chorus: Eve and morn my prayers ascending To God's heaven on wings of song Seek the joy that knows no ending The pure heart that knows no wrong. Chorus:
