G-Men Bootleg Series Vol.1 was Rory Gallagher's last official release before his untimely death in 1995.

This album was Gallagher's attempt to bootleg the bootleggers; released in 1992 it was a no-frills exercise with little production work.

The third CD is called "Bullfrog Interlude", featuring a gig for London radio to promote the then forthcoming album, Blueprint from February 1973.

The live recording of "The Cuckoo" from this gig was used on Blue Day for the Blues, and also this gig's version of "What in the World" was used for the BBC Sessions live CD.
