Guarda os teus beijos para mim - Acetato

There's some more Portuguese covers of Eurovision songs in the batch of singles I received recently. This one was released in 1976 and features the number 1 and 2 of that year's competition: 'Save your kisses for me' (UK) and '1, 2, 3' (France). In Portuguese, that would be 'Guarda os teus beijos para mim' and 'Um dois tres'. 

The tracks were recorded by Acetato, an anonymous act who released nothing else, just this one single. As a result, the names of the four members of Acetato, pictured on the back sleeve, remain unknown.

My collection: 7" single no. 6918
