Ok. The above don't ring any bells, apart from the mention of Herb Alpert.
I only recall a line or two of lyrics from back then:
If you come from Spain
And Spanish blood runs through your vein(s)
Possible something completely different, but the tune was the same.

Okay. I googled it. Apparently it was "showbusiness is in your veins"
YouTube, Spanish Flea: Kathy Kirby

Apart from the Herb Alpert instrumental, this is the version most likely to be remembered by UK Mudcatters.
