Is this lovely boy or girl a Mistle Thrush or a Song Thrush?

There are a pair of these that visit my garden a few times a day, here in Handforth, Cheshire. I'm pretty sure they're Mistle Thrushes. This isn't a great photo but he always stands very upright. I should say that this was taken in the early summer. Now they seem to have much paler chests & under-belly.
