That would be AT Phosphor:

And by the way, for those keeping score, HF&J's Cyclone is a wonderful font, able to communicate a variety of moods with surprising versatility. It sets like a charm too. Every word looks like a jewel. Man those Hoefler kids really know how to do it.

Its close to an old Erbar font, don't you think so?

Lichte fette Grotesk
Ludwig & Mayer, Frankfurt am Main
Erstguß 1924

Georg

You're right Georg, Phosphor and Red Rooster's 'Phosphate' are almost exact copies of the Erbar typeface. Letraset's 'Follies' is modified more, but still quite similar. However, the '!' mark sets the 'identical' ones apart from the Erbar design, and Michael seems right about 'Phosphor' being the answer this time.
