I remembered (correctly) that I already owned a single by Al Martino; it was his version of
Volare, which I bought over 12 years ago. While that was a hit for him in 1970, his version of 'Love is blue', which he released in 1968, was less successful. At least: it didn't chart in the Netherlands, but he still managed to reach number 57 in the US Billboard Hot 100 with it.
The back of this sleeve is a real gallery of stars: it features an advert for singles by the Dave Clark 5, Ray Charles, the Beach Boys and the Beatles. Back in those days, big stars were all over the place, and they would endure for decades. Compare that to nowadays, and you'll be blue in an instant.
