Look for the four-disc set from the En Concert Avec Europe1 series, featuring a purple banner reading "Pour Ceux Qui Aiment Le Jazz" across the top. It was a legitimate release on the French Universal label. It's hard to find but, strangely enough, can be had for reasonable prices when located. This set features the 1960 Olympia concerts with John Coltrane and Sonny Stitt. The first disc is remarkable, as the crowd whistles (boo's) Coltrane during his solo. The sound is solid, not bootleg dodgy at all. Then there's the four-disc set from Dragon featuring the Stockholm concerts with Coltrane and Stitt, also a legitimate release with solid sound.
