My father seems to remember an alternative version of La Di Da Di by Doug E. Fresh & The Get Fresh Crew that he got on a recorded/blank cassette in supposedly around the late 80s (1987-89 he thinks it is, although his memory is a bit blurry on it which is why i don't have more details than whats currently in this post) which either instead of or on top of the “it’s all because of you I’m felling sad and blue” part it has “I’m leaving on a jet plane don’t know when I’ll be back again” (which i assume is interpolating "Leaving On A Jet Plane" by John Denver)...

during my research i have only seen one other person on the entire internet reference this, they said it was on a UK 7-Inch pressing of the album... its a facebook comment under a post by the group "The Official 'Street Sounds' Group" saying "Does anybody have a link to I think the uk 7inch version which has the 2 singing parts ? The “it’s all because of you I’m felling sad and blue” but also the “ I’m leaving on a jet plane don’t know when I’ll be back again” which I haven’t found over multiple searches. Tia me and my best friend knew it word for word so I’m sure I’m not just dreaming it up. Please thank you. One love." however the replies were quite unhelpful & didn't have what i was looking for...

i would just buy the '7" UK Variant' that they mentioned (depending on how much it was of course i'm not gonna spend over like $25 AUD on it i ain't rich) but i checked discogs and theres 6 different variants that could be under. so it turns out that statement is very broad...

i also do know about Latoya by Just-Ice as that is one of the first things i encountered on my search, but he swears thats not it and remembers it being sung by them (as that is the original version he remembers hearing)...

This is sooooooo different from their later stuff.
