CNote, thats not completely correct. Gravano was on-record as an "associate" with the Colombo crew (he was never inducted as a member with them.) After getting released to the Gambino crew, he was later inducted with them.

And I think you mean "Albert Gallo," not his old brother Larry. As far as I know, Larry was always with the old Profaci/Colombo crew. His kid brother Albert (Blast) was an "associate" of that crew too. But after Larry died of cancer and their brother Joey got whacked out, Chin Gigante was able to convince the Colombo crew to release Albert to him. Thereafter, the Genovese crew inducted Albert and another former Colombo affiliate, Albert's close friend Frank (Punchy) Illiano.
