He contacted pop group Hanson in late 1997 about working together on a
song. Hanson was unable to work with Gregg due to their busy schedule,
but in 2001 Hanson contacted Gregg and wanted to write a song with him.
They turned out a song called "Lost Without Each Other", which has been
called an "infectious new wave punk-rock song". It is featured on
Hanson's 2004 release, "Underneath".
