SQL Server 2008 :: Concatenate Column Name With Values

I want to concatenate the column_names with the respective values.

Create table #test1 (Id int,Name varchar(10),Country varchar(10))

insert into #test1 values ( 1,'JOHN','USA'),
(2,'SAM','CANADA'),
(3,'HO','CHINA'),
(4,'RAM','INDIA')

select * from #test1

I have temp table with columns (Id,Name, Country). I want to concatenate column_name with their respective values; means i want column_header with every value for the column and then i want to concatenate multiple columns. I am looking for something like below:

ID values
1,NAME-john-COUNTRY-USA
2,NAME-SAM-COUNTRY-CANADA
3,NAME-HO-COUNTRY-CHINA
4,NAME-RAM-COUNTRY-INDIA

Note: This is just a sample .i am looking something dynamic because i have around 50 tables.i can do with query below but since i don't have static columns and table i am looking for something dynamic

select ID, (a+'-'+B) as Value from (
select ID,'NAME'+'-'+NAME as a,'Country'+'-'+Country as b from #test1
