ROBIN GIBB

John Travolta has released a statement on the passing of Bee Gees co-founder Robin Gibb ... calling the music legend one of the most "wonderful" people he's ever met. Robin -- along with his brothers Barry and Maurice -- put together the soundtrack for the 1977 disco classic "Saturday Night Fever" ... the flick that helped propel a young John Travolta to become an international movie star.
Travolta tells TMZ, "I thought Robin was one of the most wonderful people -- gifted, generous, and a real friend to everyone he knew. 
                                                                                And we'll miss him."
