Horace Silver - Lead Sheet of "Gregory is Here"

Horace Silver wrote this tune for his first son when he was born. Also, a young set of brothers one playing tenor, the other trumpet and hailing from Philadelphia made their debut on this record. Any guess who they might be? Yep, the Brecker brothers playing in one of their first gigs as the horn section with Horace's band. The record is called "In Pursuit of the 27th Man" Couldn't find it on amazon.com though.
