"Flying High Again" is a song by British heavy metal rock artist Ozzy Osbourne. It is the 2nd track on his 1981 album, Diary of a Madman. This song seems to pertain to the usage of drugs, with "Flying High" meaning "getting high: the use of the line "Mama's gonna worry, I've been a bad, bad boy" seems to refer to Sharon Osbourne, who Ozzy has often referred to as "Mama," worrying about Ozzy's health during his drug addiction.

It has reached No. 2 In the Mainstream Rock Charts in 1982.

There are a number of the references in the song that sound like a description of Synesthesia, or perhaps the effects of taking LSD. For example "black and white is red" could be colour number synesthesia.
