P.S. From the wikipedia entry on "New Train"...
Interesting enough "Mercury Blues" from Steve Miller's 1976 album "Fly Like An Eagle" generated considerable royalty income for noted SF Bay Area blues producer Bob Geddins who later got royalties for SRV's recording of "Tin Pan Alley".Ben Sidran gave an unreleased copy of New Train to Steve Miller, who recorded Pena's "Jet Airliner" with his band for their 1977 album Book of Dreams. The "Jet Airliner" single went to #8 on the Billboard chart. Pena's primary source of income in his later years were royalties from that single.
