I draw pictures in my book of what each line is about, e.g. "last night as i lay on my bed..." would have a picture of a bed next to it, or "I like to rise when the sun she rises" a sun rising over some steps. You should see my illustrations of 3 drunken maidens! I like celtaddicts suggestions. If I get lost I just fit the words "something or other" whatchamacallit thingamybob etc to the tune till someone helps me out.
