glueman - no. There are songs that I do that I picked up simply from listening to them being done. But as I've also said before the it is commonplace now to learn songs through an extended oral transmission - one example being youtube - in which one person sings the song to his webcam and another hears it on his computer - not in real time of course - but that's oral transmission with an additional medium interposed.

Most performers learn words from written texts - but think of teenagers who know all the words to pop songs. They have written nothing down in most cases - the input to them is wholly aural.

The songs so learned are then modified by the creative impulses of the individual.
