On March 25, the remarkable Elton John proudly turned 60 years  old. To celebrate the occasion, he performed his 60th concert at Madison  Square Garden, and two days later released a newly compiled and digitally  remastered collection of his greatest hits from past to present. This over  78-minute-long compilation is the first-ever single disc to cover the first  35 years of the great singer-songwriter's career.The Number 1's series is a brand-new line of CDs featuring #1 radio hits  from the biggest names in music. This collection includes decade  compilations as well as individual artist CDs and is being released by  Universal Music Enterprises (UMe) in its ground-breaking,  environmentally-friendly packaging format. A first for the music industry,  the standard package (both sleeve and tray) will be completely  paper-recyclable, continuing the company's long-standing commitment to  being "green."To further reduce the amount of paper in the Eco-Pack, the CD booklet will  no longer be offered.UMe is the first North American music company to replace the traditional  jewel case with recycled paperboard sleeves and the plastic tray with trays  made from PaperFoamÂ®, a new  packaging technology from Shorewood Packaging, a business of International  Paper, that is paper-recyclable and biodegradable. Shorewood Packaging is  the first North American packaging supplier to produce disc trays from  PaperFoamÂ®.
