Flower Friday...Yellow

I saw this little yellow flower poking it's head out of some shubbery today, no idea what it is, shoulder height so not a buttercup.....unless it's a very tall one! Did an hour and a half with the excercise/dance group this morning, so feel justified in sitting in the garden sunbathing this afternoon.....got to make the most of this gorgeous weather. Thanks Bikerbear for hosting :)
Have been doing a search....it might be Kerria?

Thank you very much as always for the responses to yesterday's abstract :)
