Answer:
There are two different men by the name of Randy Jackson.

The American Idol judge was NOT in the Jackson 5. He was was born in 1956.

The other Randy Jackson, born Steven Randall Jackson did often travel with his brothers, but did not join the group until Jermaine left in 1976 and the group became The Jacksons because Berry Gordy would not let them keep the name The Jackson 5.
