Gaelic song has had very little influence on the English language songs. Just a handful of macaronic songs have come through into the English language, songs like Suil Agrah, but even that song has English origins in most of its verses. Gaelic and English language song have so little in common that it's not surprising there is only minimal crossover. Any crossover is more likely to be found in Gaelic-speaking parts of Canada than the British Isles.
