jno; I suspect that they stuck with young Betties. I have read that there was more than one Betty. I remember that on a few occasions me mam parked me in the stalls and disappeared until their act was over, then came back for me with an ice cream tub and wooden spoon for each of us cos she was always in a sweat in the Hippodrome. She used to take me round to Auntie Ginny Dawber on those nights and leave me there with Uncle Jack, then pick me up in the morning with Uncle Joe (who had a business in Wigan making mint-flavoured sweets called mint balls).
My mum's first name was Eliza, which she hated because her mates called her fertiliser.
