Probably the greatest aid to memory is rhyme. Try learning the lyrics as a poem first.

Difficult ones I tend to do visually, but then I have a 'visual' mind.

Take Martin Graebe's Harry the Hawker is Dead for example. (Reminders in brackets.)

Old Harry the Hawker is dead
No more he'll bring his boot hooks and laces (start at the foot)
And fancy goods from foreign places
Old Harry the Hawker is dead   (Knife cutting a bootlace)

Old Harry the Hawker is dead
No more he'll bring his knives and forks
The finest Sheffield cutlers works
Old Harry the Hawker is dead (Knife cutting a candle in half)

Knives and forks, boots hooks and laces
And fancy goods from foreign places
Old Harry the Hawker is dead. (pins sticking in a candle)

Old Harry the Hawker is dead
No more he'll bring his lamps and candles
In holders of brass and graven handles
Old Harry the Hawker is dead.

Lamps and candles, knives and forks, etc.

Old Harry the Hawker is dead
No more he'll bring his needles and pins
In penny boxes and tupenny tins
Old Harry the Hawker is dead (Needles sewing a sash)

Needles and pins, lamps and candles, etc.

Old Harry the Hawker is dead
No more he'll bring his ribbons and sashes
To brighten our hearts with their colourful splashes
Old Harry the Hawker is dead (snatches almost a rhyme with sashes)

Ribbons and sashes, needles and pins, etc.

Old Harry the Hawker is dead
No more he'll bring his songs and snatches   
His frisky jigs and cheerful catches
Old Harry the Hawker is dead (me in a ribbon. What a joke!)

Songs and snatches, ribbons and sashes, etc.

Old Harry the Hawker is dead
No more he'll bring his jokes and smiles
Collected from England's many fair miles
Old Harry the Hawker is dead

Jokes and smiles. songs and snatches, etc.

Harry the Hawker, written by Martin Graebe.

(In the reverse)
Songs and snatches, (snatch a ribbon out)
Ribbons and sashes, (needles in a sash)
Needles and pins (pins in a candle)
Lamps and candles (knife cutting candle)
Knives and forks (knives cutting laces)
Boot hooks and laces
And fancy goods from foreign places (rhyme)
Poor old 'arry
