Welsh lyrics and translations needed

[ka roger]

Hi anyone that can help please. I am just completing an instrumental album on guitar and harmonica, with the title Acoustic Hymnal. I'm a British songwriter, long resident in the Philippines. This album will be distributed initially at my church, the Union Church of Manila and possibly released thereafter in other countries. It will also be on my website (www.song-smiths.com ) sometime early next year. I need the following help please to complete the sleevenotes. What are the most common Welsh lyrics sung to the following great tunes, and what would be good English translations of their first lines or better still of their whole texts? Aberystwyth; Blaenwern; Cwm Rhondda; Hyfrydol; Ton y Botel (Ebenezer).
