Veteran rocker Meat Loaf has confirmed rumours he has developed a stage show based on his career.

The Bat Out of Hell hitmaker has enjoyed a stellar rock career dating back to the 1970s, as well as a theatre stint in Hair and parts in movies including Wayne's World and The Rocky Horror Picture Show.

Now he has detailed a stage musical project he has been working on with U.S. composer Jim Steinman, but the star fears the show will be too expensive to ever go into production.

He tells rock magazine Q, "It's been on and off for 15 years, and a Canadian promoter has bought the rights. But Jim controls the writing. I have a script at home and it's great. But Jim's story is very extravagant so in this day and age it might be cost prohibitive. But there's always a way to figure out how to get a special effect cheaper than having to build a new theatre."
