Well when our kids were young back in the middle ages of the early 70's my husband and I would sit and watch Sesame Street while our kids woulds be outside playing.
Best to keep it in the woods if you know what I mean. Although when we're by ourselves we sound pretty darn good. I don't know Adventure Time is it a kids show? sorry showing my age i guess.
I sing to my flock all the time, right now Christmas songs, my gander loves to join in, course neither one of us can carry a tune. it's a good thing we live out in the country,
