Lifeline will only push newr sixties and seventies soul, unknown, lesser played and forgotten thinking mans (or womans oldies), nothing overplayed or oldies you hear week in week out, Mick and Andy bwant nothing else. They would sooner not promote a venue if thye had to go down the tried and tested route.
I will be there again next time, seek me out!!
As for instrumentals, I couldn't agree more, lack soul IMO. Maybe someone giving their all blowing into a sax but like you said lacks the heartbreak factor. Would sooner hear a good vocal anyday of the week and certainly haven't got time for an instrumental of a vocal.
