Tootler, yeah, definitely a sharp generational difference in my own experience of people spontaniously singing - both to amuse themselves and to participate in family do's. There's also a cultural difference in my own experience (Irish still plenty singing & dancing with younger folk/English much much less of same with younger generations). But as to the generational difference in particular, my Grandmothers would sing all the time while cooking, cleaning and ironing. But apart from me, I don't hear that happening at all now, in the homes I visit. The vast increase in electrickery powered domestic entertainments/distractions (like stereo's, phones, PC, internet and especially of course daytime telly), must have everything to do with it IMO.
