I learned How Sweet I Roamed from the unique dobro player Gene Tortora. He learned it from a recording of the Fugs and made it musically beautiful.  The text was written by the English poet William Blake in his mid teens.There are parts I don’t understand. What, for instance does “fired my vocal rage” mean? 

How Sweet I Roamed (William Blake) 

How sweet I roam'd from field to field,    
And tasted all the summer's pride, 
'Till I the prince of love beheld,          
Who in the sunny beams did glide! 

He shew'd me lilies for my hair,         
And blushing roses for my brow; 
He led me through his gardens fair,         
Where all his golden pleasures grow. 

With sweet May dews my wings were wet,         
And Phoebus fir'd my vocal rage; 
He caught me in his silken net,          
And shut me in his golden cage. 

He loves to sit and hear me sing,          
Then, laughing, sports and plays with me; 
Then stretches out my golden wing,         
And mocks my loss of liberty.
