Native Londoner myself, tho probably wouldn't be accepted as precisely a cockney ~~ tho I think my mother would have been, perhaps, tho she had little such accent in adulthood. But, try as I might I cannot decipher/translate "panna-bowwww". Could Bonzo or somebody oblige, please? I remember "ragga bowwww" = rag & bone, but that doesn't seem quite the explanation here.

I am sure the answer is something terribly obvious & I shall feel very silly...
