[4] Unlike the primal screams on "Mother", the opening song on Plastic Ono Band, "My Mummy's Dead" ends the album with John singing without emotion with a monotone delivery.

[3] Music critic Johnny Rogan finds that the song "captures the menace of childhood fears through adult remembrance in a most disturbing fashion".

[1][2][3] Two takes of "My Mummy's Dead" were recorded in Bel Air, California, during the summer of 1970 as part of the demo tapes Lennon made in preparation for Plastic Ono Band.

[6] Authors Ben Urish and Ken Bielen describe "My Mummy's Dead" as "brief but powerful", stating that it produces a "memorable and chilling" effect and appropriately ends John Lennon/Plastic Ono Band by "capturing the essence of psychological pain and intimating at its persistence".

[3] Music critic Wilfrid Mellers describes it as a "sickening cross between nursery rhyme...and TV commercial jingle" that takes us back to childhood in a "disabused and disillusioned" fashion.
