Maybe based on Souvenir Bold ?

Thanks to both of you.

I'd say that's a pretty good starting point. I think a lot of people don't realise how easy it is to alter one or two key letters in a font, particularly when its only required for a few words of text. Claude's suggestion covers the G S T that don't fit and with those two fonts and 10 minutes playing around you could replicate Good Times very easily. Someone will probably identify a font with all the attributes now but sometimes it's quicker to adapt what you have than search for another font.

The exact font would be OPTISouvenir Bold. That's how you get the swashes if you open the character map after downloading it, depending on if you have a Windows PC.
