Got lots of song fragments lying around? Join two (or more) separate incomplete song together to make one whole song. Good for co-writing (A Day In The Life) or using up your own random ideas (I Am The Walrus).
Try to make sure there is some musical, lyrical or thematic common ground between the fragments eg lots of time changes (Happiness Is A Warm Gun), multiple characters – (Pam, Mr Mustard, Sun King, Her Majesty - The Abbey Road Medley), similar chord progressions (I Got A Feeling).
I've Got A Feeling, A Day In The Life, Dig A Pony, I Am The Walrus, Happiness Is A Warm Gun, You Never Give Me Your Money, Carry That Weight
also Layla (Derek & The Dominos), Zooropa (U2), Fall At Your Feet (Crowded House), Paranoid Android (Radiohead), Believe It When I See It (Ron Sexsmith)
