Isn’t there any legal issue with naming the album after the place?

There might have been if Marvin wasn’t asked first.  The band checked with him as soon as they decided that’s what they wanted to call the album.  Not only did he agree to allow them to use the name, but he even let them take apart some of the machines to record the innard sounds as well as just the typical atmospheric jumble of tick-tocks, clink-clanks, plink-plonks, buzzes, whirly-do’s, whistles and bells that you hear when you walk around the Marvelous Museum of Marvin’s.  You’ll hear them throughout the CD.
