Willie and Julio’s version went to number one on the Billboard country music chart, number 5 on the Hot 100 chart, number one in Belgium and Canada, and was a top ten hit in several other countries.
The song was Nelson’s greatest hit in Europe, and Iglesias’ biggest in North America. In the years since its release, it has been covered numerous times, including versions by Merle Haggard, Tom Jones, Engelbert Humperdinck and Alanis Morissette.
