[78-L] Follow-Up Songs

[Kristjan Saag]

Eddie Calvert tried to follow upp his 1953 hit "Oh Mein Papa" with a 
similar number, the (partially) self-penned "My Son My Son" in 1954.
A few years Tommie Connor & Johnny Reine  wrote a follow-up to "Lili 
Marlene": "The Wedding Of Lili Marlene". It was a big hit for Anne 
Shelton in the UK and a minor hit for The Andrews Sisters in the US.
Does anyone know of other such obvious follow-ups, theme-based or 
otherwise connected?
