Spanish singer Soraya (from Cáceres) brings back this old hit by Spagna in a perfect BrE with a touch of AmE as well.

A very simple unpretentious song with a catchy rhythm. That's the cute thing about it.
A girl has been alone for a long time, she needs love, maybe she's a bit or a lot desperate about it. One day she meets a boy, they have a good time together and she gives him her phone number in the hope that they can meet again and start a relationship. But he's not calling, not yet, or maybe she's so impatient that she can't wait, so she's telling him, "call me!"
