"Someone baked me a cake. It's made my knees feel a bit tingly, but thank you," announced Kathryn Williams to introduce the first date of her UK tour with guitarist, singer and producer Neill MacColl.

"Are you suggesting that someone spiked the cake with knee drugs?" came the quick response from her new collaborator. Never one to take herself too seriously, Williams has found a perfect partner in MacColl in terms of character, chemistry and musical compatibility.

During an evening peppered with such banter, the duo introduced an audience they observed as being "well-behaved" to sweet and heartfelt lyrics wrapped in beautifully simple acoustic melodies.

Sweet is what Williams does best, but her forays into a more experimental, jazz-infused interest, including a looping and breathtakingly powerful rendition of Hallelujah, made it startlingly obvious there is much more to come from this voice.
