As the landscape bursts back into life, we celebrate spring. We don't just see the season changing around us - we feel it, smell it, taste it and hear it. Spring isn't just a feast for the eyes - it awakens all our senses. Five of our presenters each discover their own sense of spring. Matt Baker gets a real feel of spring in north Wales, where he meets a hotchpotch flock of orphan lambs. Ellie Harrison journeys through the Top of the Spring Pops - gathering seasonal sounds of nature to soothe the soul. Anita Rani gets a rather unusual taste of spring at a barbecue with a difference, while John Craven captures the ultimate smell of spring with a scientist known as Doctor Smell!
