John Travolta -- Robin Gibb was a 'Real Friend'


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."
