The mix-CD that ex-Beatle Paul McCartney created for Steffina Graves, his new girlfriend, is a 'sweet gesture,' but 'limited in terms of variety,' according to the 27-year-old Graves. ''Baby I'm Amazed' may be great, but I don't know if anyone needs two different versions,' Graves said Tuesday. 'And I'm not sure anybody really liked 'Say Say Say.'' Graves, however, praised the psychedelic, Sgt. Pepper-inspired collage of McCartney photos on the CD cover and booklet as 'very creative,' and noted that 'At least the CD has one Badfinger song on it, even if it is a cover of 'Love Me Do.''
