Bob Dey's Tank Engine Band is called this because it is Bob Dey's band, though he is not a performer. The only performer that is Bob Dey's Tank Engine Band is called Mr. Talent 2005, who is the recipient of that title through his talented skill. This same skill is that which made him an interest of Bob Dey and filled his days with working for that man.
Now you can hear Bob Dey's music performed by Mr. Talent 2005, while Mr. Dey himself can go about his own, very time consuming, business.
Thanks for reading this, but don't forget also to listen.
