After listening to the "I have a dream speech" a number of times and i have decided that the sort of voice in the speech does not really go hand in hand with what i am aiming for, so i have decided that i will record the vocals in the song myself, and also this way i will be able to add in extra bits if i want to and if i think they will fit in well with the music track, i also think that this will add more depth to the music as i will be able to change my voice to whichever key i think is suitable for the track.
