I learned "El Paso" in 1979 from Wilfried Drygala (a Marty Robbins fan amongst many of his interests) and we performed it very often in the
Idle Fellows. My part was to join in the chorus and look intelligent while fiddling and fumbling with my penny-whistles as Wilfried got on with the story-telling. Actually, Wilfried did it jolly well and it was great fun to sing, especially the wailing bit in the chorus (... West Texas wi..................nd).
Since going solo I'm still working on it trying to do a concertina version. It's a fine cowboy song of love, jealousy, duelling and finally dying in the arms of one's beloved after a heroic gun battle with pursuing lawmen. A real ballad!
