It is Steven Brown reading ‘You say you love’, a poem that has proved hard for experts to date, but which is generally thought to be an early attempt by Keats to write love poetry. It wasn’t published until well after his death.
Tempting though it is to relate everything Keats wrote to an incident in his intense relationship with Fanny Brawne, this is thought to have been written well before he met her. It was probably addressed to Isabella Jones, an older woman Keats was involved with in 1817, at least a year before he met Fanny. Indeed it seems most concerned to describe the physical demonstration of love and perhaps suggests a youthful, slightly petulant response to a lack of commitment from a beloved.
