Picture Puns

Below are a series of picture puns: pictures grouped in such a way that they represent common phrases or names. There are 23 of them. Can you work them all out? They are based on homophones. Some are easy, others hard. The only extra clues I give are 'number of words in each phrase'. Musical notes ie A, B, C are counted as a word. Two words joined by a hyphen are considered one word.
