Love is the sweetest thing, and so it is. But ................

Bert was committed to the idea of the industrial working class having a living tradition of songs which reflected the life,times and struggle of said workers akin to the living tradition,although fading, of the agricultural class.

Lots of songs exist that were written about the lives of industrial workers, miners, sailors, cotton workers etc. But it seems that Bert couldn't stop himself adding to that collection.

Nowt wrong with that, as others have said, but what was Bert and what was collected?
