Just in case you missed it on Adams facebook:
“My 7″ double-A side featuring covers of Motörhead and David Bowie turned out very nice! It’s out 22nd April on very limited clear blue vinyl via Club AC30 for Record Store Day 2017, available in all good participating stores.”
Iron Horse/Born To Lose/Thursday’s Child
This appears to be a UK only release at the moment, nothing official of course.
