Has anybody seen my youth?

Has anybody seen my youth? i left it here I could have sworn I've looked in the loft and I've looked in the shed I've even looked underneath the bed I've been round to the neighbours to see if its there and I've looked in the cupboard under the stair I've searched in every nook and cranny I'm telling you this is really uncanny because all at once I looked and it was gone Just like those endless summer nights

Tell me has anyone seen my youth?
