Celebrating midwinter in sub-Antarctic. Olivia Harrison on celebrating her husband though poetry.

As we celebrate the summer solstice - the longest day north of the equator – of course this means on the other side of the world it is the shortest or mid-winter. For the first time the British Antarctic Survey have got an all-female team wintering on Bird Island in the sub-Antarctic. Midwinter is a moment of celebration for the teams on the British Antarctic Survey sites where they have a big meal and give each other presents. The Bird Island Research Station Leader, Imogen Lloyd, joins Emma to tell her about her team and the work they are doing. Olivia Harrison has penned a book of poetry called Came the Lightening to celebrate her husband, George Harrison's life, more than twenty years since he passed away from lung cancer at the age of 58. As lead guitarist of The Beatles, his most famous songs include While My Guitar Gently Weeps, Within You Without You, Here Comes the Sun and Something. So what was it like to be married to a musical icon? She tells Emma what prompted her to share her memories in poetry.
