Spanish pop groups were an unusual presence in the UK charts in the 60s. Los Bravos, though, managed to get to no 2 with their first single release in Britain in 1966.

I can’t say I remember they had another ‘hit’ but Wikipedia begs to differ. I’ve listened to both the singles listed in that link as UK hits and absolutely no bells rang.

I’ll count them as one-hit wonders.
