Hi-this Has Been Driving Me Nuts For Years Now, So Here I Am. I Heard This On Some Christian Radio Station. It Is Sung By A Black Male Artist - Gospel I Think, With A Black Choir Backup. The Lyrics Go Like This: Behold, I Tell You A Mystery, We Shall Be Changed, Be Changed In A Moment, In The Twinkling Of An Eye, Yes Be Changed In A Moment, In The Twinkling Of An Eye, When The Last Trump Sounds, Be Changed. If Anyone Out There In Cyber World Can Help Me, I Would Be Soo Thrilled! Thanks In Advance
