[1st verse:]
 
 Barnum and Bailey were wonderful showmen
 
 In the theatrical world there are no men
 
 Who would claim to be their equal
 
 And the sequel
 
 Was, they made the "tin," packed them in ev'ry season
 
 I know it well and I'll tell you the reason
 
 They were a pair of handbill throwers
 
 Horn blowers
 
 You must talk about yourself
 
 Or they'll put you on the shelf
 
  
  [Refrain:]
 
 Blow your horn
 
 Let 'em know you're comin'
 
 Blow your horn
 
 That'll start 'em hummin'
 
 Just make a whole lot of noise
 
 The only way to collar ev'ry dollar is to holler
 
 Mister Barnum said
 
 Ev'ry other minute
 
 There's another one born
 
 You'll strike it
 
 Just like Barnum
 
 Make 'em like it
 
 Gosh darn 'em
 
 Yell out
 
 You'll sell out
 
 If you'll only blow your horn
  
 
 [2nd verse:]
 
 Some people argue against advertising
 
 How they can feel as they do is surprising
 
 I'm a walking eight sheet poster
 
 I'm a boaster
 
 The red, white and blue and its value was doubted
 
 Till Georgie Cohan started singing about it
 
 Now, ev'ryone who was against it
 
 Commenced it
 
 You will be a household word
 
 If you just make yourself heard
