Took my son and his tear stained face out of Sunday School As Chapel Hymns began to fade away Left his mother with the other as we drove across our town Going to the place where the seagulls and the cranes play On a Sunday over Cardiff Bay This is one day of our lives And on a Sunday over Cardiff Bay Know that I love you All of my life And the old man in the side street he made you smile Waved at us both so we both waved back Down on through Bute Street to the mud of the low tide They tear the old things down my son, but some things stay the Same On a Sunday over Cardiff Bay This is one day of our lives And on a Sunday over Cardiff Bay Know that I love you All of my life Saw Captain Scott on the Terranova Setting sail for open sea And mayeb one day when you're older You'll come down this way and think of me It'll be a Sunday over Cardiff Bay Just one day of your life And on that Sunday over Cardiff Bay Know that I loved you. On a Sunday over Cardiff Bay This is one day of our lives And on a Sunday over Cardiff Bay Know that I love you I hope that's alright All of my life
