Anime childhood classics – Dogtanian, Willy Fog & Tom Sawyer? (also Flash Gordon?)

I’ve been looking for these old series from my childhood. Can someone help me, please?
I’ll give more details here, but please forgive me for any bad english:

Tom Sawyer no Bouken
I found two threads with this one. One is very old and closed (2008, megaupload links), and the other is not the version I’m looking for. It has 13 tracks, but the one I’m interested is the one below, with 12 tracks, that looks more in sequence with the series

The main attraction is the ‘Jigoku no Joe’ track, which seems to refer to the character Injun Joe, and is not present in the ’13 tracks’ version. One of the scariest villains from my childhood.

La Vuelta Al Mundo DE Willy Fog / Around the World with Willy Fog
I found a version with 8 tracks here:

Thread 224019

But is mainly songs. Does anyone know if there is an instrumental one? And if so, can you share it?

D’Artacan y los Tres Mosqueperros / Dogtanian and the Three Muskehounds
I didn’t find any link for this one? Does anyone have it that can share?

Thank you, everyone, for you attention. And even if you can’t manage to get the links, thanks anyway.

P.S.: Real sorry for pushing it (and it isn’t about japanese animation either), but since I’m on the subject of childhood music… I keep still looking about some kind of soundtrack from ‘The New Adventures of Flash Gordon’ (1979) animation from Filmation Studios, or it’s movie version (also animated, don’t confuse with the ‘Queen’ one). I kind of don’t believe it exists, but always have hope.

P.P.S.: Once again, Thanks anyway
