A table with random values from each table

I have 3 table .a,b,c .The Name whose datatype is varchar .I need a query that will get one row from each table and give me a another table namely 'd'.This d will have 3 rows for eg. a1 above b3 above c2 ..these values in table d are random every time I run this query ..

 Table a   Table b   Table c 
 Name      Name       Name  
 a1        b1         c1  
 a2        b2         c2 
 a3        b3         c3

when i run the query I need a table 'd' with random

Table d    Table d
 Name       Name
 a2         b1
 b3         a3
 c1         c3

and there is no relation between these tables !

1 answer: sort voted first
declare @TableA table (name varchar(10))
declare @TableB table (name varchar(10))
declare @TableC table (name varchar(10))

insert into @TableA select 'a1'
insert into @TableA select 'a2'
insert into @TableA select 'a3'
insert into @TableB select 'b1'
insert into @TableB select 'b2'
insert into @TableB select 'b3'
insert into @TableC select 'c1'
insert into @TableC select 'c2'
insert into @TableC select 'c3'


--TableD
select (select top 1 name from @TableA order by newid()) as Name
union all
select (select top 1 name from @TableB order by newid())
union all
select (select top 1 name from @TableC order by newid())
