Cross-pollination is nothing new when it comes to the music we often hear at the end of our program.

Today's Global Hit is no exception.

The Hay Brigade is a group based here in the US, but its musical roots stretch all the way to the UK.

We're listening to music from The Hay Brigade right now and we'll hear from the group in a moment. But for some perspective we turn first to Brian O'Donovan.

He's host of the WGBH weekly radio program A Celtic Sojourn and a champion of music from across the pond.
