You were Christian Coulson's husband and you both got a 6 months old daughter, you loved medieval and old things so you literally have a piano to a castle that you love, you live in it.

You were holding your daughter on your hip while playing the piano, you were in Middle Age's man clothes and you were playing "Golden Brown" by The Stranglers on the piano and you were singing the lyrics too.

Your daughter was loving it and watching in awe her father playing piano in his Middle Age's outfit. Your husband wasn't there because he was in the castle, not knowing that his husband was playing piano outside with their daughter on his hip.
