Singaround is almost as much a catch-all term as a folk club. Folk clubs local to me are mainly a mixture of singaround and guest evenings, with the difference being the balance between the two. The two folk clubs I regularly go to have a guest once a month with a singaround the other three weeks, but others have a different balance. Also the content of singarounds can vary. One I started out with was more of the sixties accoustic evening with mainly accompanied singing, but tunes and unaccompanied trad were certainly welcome. The ones I now go to are a mixture of traditional song and recently composed song in the folk idiom, sometimes accompanied, sometimes unaccompanied and it seems to be pretty much the pattern locally.

The suggestion that singarounds are "sixties accoustic evenings" is simply an incorrect generalisation, though it may be that that is how it seems in some areas.
