In Gredos 2010 someone shouted very loud in spanish "Ole tus huevos", that is something like "How good are you" but with reference to their male atributes, which is a very tipical spanish sentence to encourage or thank someone who does something very good or something very brave
Everybody laughed when that happened and its listenable at the simfy recording, but I cant remember in which song that happened
Also in Valencia 83 recording you can listen people talking in valenciano, which is the language we speak at Alicante, Valencia and Castellon region (and its the same that people in catalonia speaks but with lot of differents words, expressions and accents) things like "cut that man
