宝子，你一问我也想知道了呢😄
搜了一下找到了：
Teddy is played by Irish actor and musician Ger Kelly, who performs music under the name Frowning Hours, and the song he sings is a traditional folk song called “A Stor Mo Chroi (Treasure of My Heart),” a 19th century Irish folk song written by Brian O’Higgins, a writer, poet and Irish republican who was a founder and leader of Sinn Féin. The song, which has been covered by The Chieftains and countless others, speaks to the heartache of a person leaving their Irish homeland, with lyrics that include wistful lines like, “For the stranger’s land may be bright and grand/ and rich in its treasures golden/You may pine, I know, for the long, long ago/ and the love you’ll soon be leaving.”
