Old 45 of The Who

[Dan Scurio <dscurio@sprintmail.com>]

I friend at work has an old 45. Here are the details.
Side a:Pinball Wizard(2:55)/b: Dogs Part Two(2:21), The Who Vocal with 
Orchestra, Produced by Baron Lambert and Chris Stamp on Decca Records, 
Track Music , Inc. 732465(7-121,165).

Interesting collectable, eh?  Would anybody know the value of this? What 
is The Who vocal with Orchestra?  I learned what Kit's real name is.

BTW, there is no date on this record.
