PHILADELPHIA (CBS) — The Philadelphia Music Alliance welcomed seven inductees into the Philadelphia Music Walk of Fame today.

From jazz legend Billie Holiday, to glam metal band Cinderella, to WOGL DJ Harvey Holiday and Andrea McArdle’s Broadway’s original Annie, this year’s class of inductees spans the musical spectrum.

“To me, this is one of the greatest days of my life.”

Earl Young, founder and drummer for disco, soul group The Trammps, boasted a huge grin as the group’s bronze plaque was unveiled.

“Motown had their day, Memphis had their day and this is Philadelphia, honoring our own.”

His marker will go beside those for Ray Benson, founder of Asleep at the Wheel, and the legendary Roots, an honor Amir Questlove Thompson says comes full circle. He called Young an inspiration.

“I’m truly overwhelmed to be mentioned in the same sentence as the man who literally invented disco.”

Comedian Jimmy Fallon is expected to attend a gala to honor the inductees to night at the Fillmore.

The Philadelphia Music Alliance will also honor Frank Giordano with the Platinum Award for his work with the Philly Pops.
