A collection of hymn-tunes and a few other compositions of Morris Eddie Evans (1890-1984), maintained by the composer from 1906 to 1972 or later. Most of the tunes constitute a series numbered by the composer 1-148 (127 and 128 missing). The other works are four rhapsodies (pp. 34-42, 44-7, 52-4), 'Barcerolle' (pp. 65-9) and 'Largo' (pp. 144-9), all for organ, and a few songs. Most of the tunes are given words (mostly Welsh), some are dated, some have details of entry in 'eisteddfodau'. The tune 'Pantyfedwen' is on p. 124. There has been much pasting in of revised and additional tunes and words, some from printed 'Detholiadau'.
