Yes venues have changed and are getting less! Folk clubs tend to give an opportunity to sing as and when they happen ~ I reckon 3 songs in 3hrs is usual depending upon circumstances ~ less time when a professional guest is booked

Time for a guest solo used to be 2x 30mins ~ but again I have seen 2x 45mins is too much!! again duos and bands vary too

Hot spots and the like give local stalwarts time to sing and present songs

The change of attitude from singing for money by many, changes the outlook although professional and semi professionals do try to make a living ~ venues and pas etc may also reflect the type of club and singing style and arrangements of for example traditional songs

Tune sessions tend to be just that~ mixed sessions give chance for songs too ~and of course ~ audience members are invaluable for joining in and contributions ~ although not all clubs carry a "kitty" for booking guest ~charity donations seem quite popular and do aid the "living tradition" of songs
