On May 2, 1970, The Jackson 5 appeared in their first official concert as Motown headliners. They performed at the Civic Auditorium in Philadelphia, Pennsylvania. To promote their new group, Motown took out an ad in the local Black newspaper, announcing not only the concert, but the time of their incoming flight. The mob scene of screaming fans waiting at the airport surprised everyone.

Here's a photo of Michael sleeping on the plane on his way to Philadelphia, unknowingly enjoying his last few minutes of being a regular kid before instant super-stardom would hit.

Motown sent a camera crew along to film their arrival at the airport and their concert, so they could create a short promotional film for booking agents. The footage shows the group rehearsing for the concert with Suzanne DePasse, and has a voice over by Suzanne's cousin, Tony Jones, who was put in charge of promoting the J5. Portions of the footage were recycled a year later in their Goin' Back to Indiana special, and their May 1970 reception of screaming fans at the Philadephia airport can be seen in the first minute of this clip from the 1971 special http://www.youtube.com/watch?v=am5aEOfnFD8
