| Mama, do you remember the old straw hat you gave to me | |
| I lost the hat long ago, flew to the foggy canyon | |
| Yeah Mama, I wonder what happened to that old straw hat | |
| Falling down the mountain side out of my reach like your heart | |
| Suddenly the wind came up | |
| Stealing my hat from me | |
| Swirling whirling gusts of wind | |
| Blowing it higher away | |
| Mama, that old straw hat was the only one I really loved | |
| But we lost it, no one could bring it back like the life you gave me | |
| Suddenly the wind came up | |
| Stealing my hat far from me | |
| Swirling whirling gusts of wind | |
| Blowing it higher away | |
| Mama, that old straw hat was the only one I really loved | |
| But we lost it, no one could bring it back like the life you gave me | |
| Like the life you gave me |
| Mama, do you remember the old straw hat you gave to me | |
| I lost the hat long ago, flew to the foggy canyon | |
| Yeah Mama, I wonder what happened to that old straw hat | |
| Falling down the mountain side out of my reach like your heart | |
| Suddenly the wind came up | |
| Stealing my hat from me | |
| Swirling whirling gusts of wind | |
| Blowing it higher away | |
| Mama, that old straw hat was the only one I really loved | |
| But we lost it, no one could bring it back like the life you gave me | |
| Suddenly the wind came up | |
| Stealing my hat far from me | |
| Swirling whirling gusts of wind | |
| Blowing it higher away | |
| Mama, that old straw hat was the only one I really loved | |
| But we lost it, no one could bring it back like the life you gave me | |
| Like the life you gave me |
