As many of you reading this may already know, Seal is to play New York City's Radio City Music Hall next month.
The show, touted by organiser GQ magazine as being his only live performance this year, will feature as part of the magazine's "Men of the Year" awards ceremony.
At this time I have no further information regarding the concert, but should any come my way, I'll be sure to let you know.

UPDATE
Thanks to Angela on the Seal mailing list, I can now supply details of the concert.
It will take place on Wednesday, October 21st, 7 pm at Radio City Music Hall.
Tickets are available from most good agencies, including TicketMaster, costing between $45.00 to more than $100.00. As an example, a $65 ticket gets you a seat on the first mezzanine - assuming there are any left there!
The tickets are labelled "Seal in Concert", so it looks like this is a full blown gig, not just a performance at the award ceremony.
