What is the main conflict in The Singer's House by Seamus Heaney?

In "The Singer's House," Heaney uses his poetic abilities to appeal to another artist—his singer friend, David Hammond. The poem was written after Hammond canceled a recording session, following a terrorist bombing. Heaney wanted to encourage Hammond that his voice counts, and that it was important for Hammond to inspire his fellow Irish countrymen and -women with his songs. Heaney was hoping to inspire a revival in Irish language and literature, which had been largely replaced over the centuries by the language and culture of British colonizers.
