Can anybody tell me which font this is? thanks in advance!

Bookman Bold Swash  Suggested by claudeserieux 
ITC Souvenir Bold  Suggested by frd 

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.
