I think as fa as our family was concerned Mum was the Maestro at faking songs.
Not only did she here you sing a song and join in with a totally different tune but the worst was when she made up notes for a song most memorable was " fight the Good Fight with all your heart": Akiiki's version with "made up" notes....Doh Mi So So mi Soh Fah Mi Reh Doh..."
