how about issuing a CD box set including all the songs he has sang background vocals on .......
CD box.... that'd have to be a CD crate

You only have to look at Poco's discography to realize how important compilation albums are;
(from Wikipedia)
http://en.wikipedia.org/wiki/PocoThroughout the years Poco has performed in various groupings, with the latest version still active today. With 24 original albums and 27 "Best of" and anthology collections, the band boasts a total catalog of 51 releases.
You haven't made it until you have a "Best Of" disc.
Some of my favourite Schmit tracks are his non-album stuff
Carry On. One Big Wave, Leave It All Up To Me and
I Only Have Eyes For You etc as well as the live radio sessions.
