I was sure you were right, Sue. I guess I saw Robert Goulet sing it on a TV show or something, but he was not the one to have a hit with it. I found this kind of interesting. It’s from Wikipedia:
"Somos Novios (It's Impossible)" is a song written by the premier Mexican bolero composer Armando Manzanero. The song was translated into English by Sid Wayne and first recorded by Perry Como in 1970. It is one of the most popular boleros of all time. Besides Como, it has been recorded by Elvis Presley, Andy Williams, Jerry Vale, Dennis Brown, and Andrea Bocelli. Tejano group Mazz recorded this as part of a meledy entitled "Canciones De Amor" which was on the album "Para Nuestra Gente".
The Perry Como version would be one of his most influential records, and in February 1971, it became his first song to reach the top ten of the Billboard Hot 100 in more than 12 years, peaking at number ten. The song's peak on the Hot 100 chart came just weeks after concluding a four-week run atop the Billboard Easy Listening chart.[1] On the UK Singles Chart, the single reached number four in 1971.
Anyway, it is a lovely song. Thanks for posting it.
