It is painful to relive things that have caused emotional crises or whatever and find ways to express that musically.
Eric ClaptonWould you know my name If I saw you in heaven Will it be the same If I saw you in heaven I must be strong, and carry on Cause I know I don't belong Here in heaven Would you hold my hand If I saw you in heaven Would you help me stand If I saw you in heaven I'll find my way, through night and day Cause I know I just can't stay Here in heaven
Eric Clapton
