No, he didn't, Chris. Barry did the falsetto, Robin did the high lines with his unmistakable vibrato, and Maurice, whose voice was admittedly not as good as his brothers', did the choruses and harmonies. Mo did do the high vocals on the pre-disco stuff. He was already very capable of doing falsetto singing as you hear it in songs like Please Read Me. He also did the falsetto on Nights on Broadway when they performed it live. Mo sang the high harmony on the early stuff with Robin in the middle and Barry on the bottom. Either that or Mo was on the bottom, it was very interchangeable. He sings the high harmony of I've Gotta Get A Message To You, Melody Fair, Kitty Can, To Love Somebody. He naturally is the lowest singing Gibb brother, especially on songs like Lay It On Me and Suddenly, but he had a very strong falsetto and an extensive head voice. I think a few reasons he wasn't the one who sang the falsetto was that Barry had more of the look as the leading man in a band, Mo had serious alcohol problems when the disco era was starting up and may have been unreliable, but most likely it's cause his falsetto sounds better in a harmony setting while Barry's had lead vocal capabilities, sort of like Brian Wilson of the Beach Boys in that they both can sing a whole song in falsetto. I don't think Mo could do that, but rather do it for a small section of a song.
