Watch IRON MAIDEN's BRUCE DICKINSON Sing A Cappella Version Of 'Road To Hell' In Houston

Video footage of IRON MAIDEN singer Bruce Dickinson belting out an a cappella version of the song "Road To Hell" during his February 23 spoken-word show at Stafford Centre in Houston, Texas can be seen below.

"Road To Hell" originally appeared on Bruce's fourth solo album, "Accident Of Birth", which was released in 1997, through Castle Communications sublabel Raw Power in the U.K. and CMC International in the U.S. In addition to being Dickinson's second collaboration with guitarist/producer Roy Z, the LP marked a reunion between Dickinson and then-ex-IRON MAIDEN guitarist Adrian Smith; both Dickinson and Smith would later return to their former band in early 1999.

Dickinson's two-month North American spoken-word tour kicked off on January 17 in Fort Lauderdale, Florida and will run through the end of March.

Bruce's spoken-word show is split into two parts. The first section sees him take a humorous and often satirical look at the world from his own very personal perspective, treating the audience to private insights into his drive and ambition, peppered with plenty of MAIDEN anecdotes, and a myriad of other experiences encompassing not just the giddy heights but also the extreme lows, as told first-hand in his inimitable anarchic style, punctuated with photographs, videos and sometimes even erupting into song a cappella, to illustrate a point. The final section of the evening is devoted entirely to the aforementioned question-and-answer session, with the opportunity to pose questions on any subject whatsoever. As Bruce's answers are all completely improvised — the more left-field and quirky the question, the more interesting and compelling the response is likely to be.

Dickinson is considered one of the world's most storied musicians. Aside from decades spent delivering high-octane performances with his larger-than-life persona in IRON MAIDEN, Bruce has lived an extraordinary off-stage existence too. A true polymath, his accomplishments include: pilot and airline captain, aviation entrepreneur, beer brewer, motivational speaker, film scriptwriter, twice-published novelist and Sunday Times best-selling author, radio presenter, TV actor, sports commentator and international fencer — to name but a few.

Dickinson, who had a golf gall-size tumor on his tongue and another in the lymph node on the right side of his neck, got the all-clear in May 2015 after radiation and nine weeks of chemotherapy.
