One of the hardest moments of singer Katie O'Donnell's life was finishing the lyrics to a song based on her friend Tayla Hancock's poem, after Tayla died from cancer aged just 16.
Now she has extended the ballad, On the Inside (Tayla's Song - Butterfly Edition), pledging part of the proceeds to children's charity Variety.
Suzi DeMarchi and Nuno Bettencourt helped Ms O'Donnell extend and record the poem. Tayla was diagnosed with osteosarcoma in 2008 when a tumour was found on her left knee. Ms O'Donnell said Tayla bravely battled the cancer that moved to her lungs."I thought it would be really nice to finish Tayla's poem, because she had such a positive message to come out of something so horrible," she said.
