Play It in My Head

I'm not supposed to play the piano when I'm all alone Or sing along to melodies all of my own So though I have perfect pitch and a rather perfect ear I'll never play a song in my case somebody else is near So, yes, I'm rather bored and could use some release But it's hardly worth the risk, I think you'd easily agree I could play a rocking solo Yes, believe me, I could shred But I'm a careful lad, so I'll just play it in my head
