Gamzilla is right, "I hear they’ll hang you upside down stretched across two boards for hearing distant voices and crossing to the Lord." That refers to when Peter was crucified. Before Jesus is crucified, he tells Peter that he will deny Jesus three times and he does so. In the end of the book of John, when Jesus has risen from the dead and come to speak to Peter. He asks Peter if he truly loves Him, three times. Each time for the times Peter denied Him. He finally states that he does love Jesus. Later on in His life, Peter is crucified for his love of God and doesn't deny it. As they are about to crucify him, he is asked to be crucified upside down, because he believes he is not worthy to have the same death as Jesus.

"I know that one day soon a song shall rise you’ll hear it with the sleep still in your eyes" Mark says that, it was very early, just before sunrise when they found Jesus' tomb empty. The song that rose is Jesus Christ, because He rose from the grave. (Mark 16:2)
