A decade ago, Glen Hansard started a Christmas tradition: busking on Dublin’s Grafton Street on Christmas Eve in order to raise money for homeless charities in town. It’s become a tradition, and plenty of other Irish musicians have joined in over the years. For the second year in a row, they couldn’t do the usual Grafton Street hang due to COVID restrictions. Instead, they put together a series of performances from St. Patrick’s Cathedral, with all proceeds going to Dublin’s Simon Community.
