Diana, I found this, but I'm not sure it's what you are looking for....do you have any other clues? There were 10 pages of hits for 'Join the Circus lyrics'.

JOIN THE CIRCUS

WHEN I WAS JUST A BOY
PLAYING WITH MY TOYS
DAD CAME TO ME SAID
SON YOU'LL SEE YOU'RE NOT LIKE OTHER BOYS
LIFE IT'S WHAT YOU MAKE
IT'S WHAT YOU TAKE WHEN YOUR GROWN
SOON YOULL SEE THE SIGHTS THAT BE
WHEN YOU'RE FAR FROM HOME
FIRST BIG LESSON CAME FROM SCHOOL
LEARNING ALL THEIR RULES
PROGRAM ME SO I COULD BE
AS BLIND AS THE OTHER FOOLS
OUT OF THE CLIQUES AFRAID OF THE CHICKS
LEARNING ON MY OWN
CAN'T WAIT TO BE FREE,
SOON THEY'LL SEE I'M NOT LIKE OTHER DRONES
FINALLY I BROKE OUT AND MOVED
TO A COMFORTABLE SITCOM
BUT THE CIRCUS OF PEARS DEMANDED
ATTENTION AND SAID TO MEE
BE OUR SPECTICAL, BE OUR SILLY CLOWN
JOIN OUR MAD PARADE, JOIN OUR HAPPY TROUPE
BE OUR SONG AND DANCE, BE OUR LITTLE PUPPET
JOIN OUR PRETTY SHOW, JOIN OUR PRETTY CAST
THIS IS YOUR'E LIFE AND YOUV'E BEEN DECIEVED
THOUGHT YOU WERE ON YOUR FEET
BUT YOUR'E REALLY ON YOUR KNEES
THE BODIES IN DEMAND IT'S JUST WHAT THEY NEED
OILS THEIR GEARS AND FUELS THEIR MACHINES
