I feel that there was also a slight mixup with the Plant Variety Rights name of Simplano. The breeders code was SIMpalno and Nola Simpson would have been doing the paper work the year after her husband John had died. Palno (a mixture of no pal) is more logical and it appears in the 1980, 1986, 1993 and 2011 references.

As for the synonym, ‘Happy Day’ - this rose was consistently known as ‘Velvet Lustre’ in New Zealand. The only reference I have been able to find for the synonym ‘Happy Day’ has been 1993 Modern Roses 10. I can’t help feeling that there was also a bit of a mixup there with Sam McGredy’s 1987 ‘Happy Days’.
