Brush Script  Sugerida por LeFly 

The red underlay seems to be Brush Script. You can recognize the 'brush serifs' top-left on the 'R's and mid-right on the 'L'
The yellow is just a fat outline around this, and the white-ish inline is neon tubing fitted to the 'centerline' of the characters.

Right, it seems so obvious now. thanks
