 Julian began to see his father more regularly . Lennon bought Julian a Gibson Les Paul guitar and a drum machine for Christmas in 1973 , and encouraged Julian 's interest in music by showing him some chords . " Dad and I got on a great deal better then , " recalls Julian . " We had a lot of fun , laughed a lot and had a great time in general when he was with May Pang . My memories of that time with Dad and May are very clear — they were the happiest time I can remember with them . "
