Though she is too young to remember Sandy Denny, Lavinia Blackwall's performance in Manchester impressed me.

Graham Robson, in Brighton, was impressed too; At the other end of the spectrum, tambourine-wielding Lavinia Blackwall was the most 'Sandy Denny' with purity of tone and clarity of interpretation defying her youth. She shimmered her way though A Sailor's Life, which cascaded slowly into an epic pool of abandon.
