I think this is such a sweet one for Tis Rhubarb, but I will warn you I can't carry a tune to save my life. I was trying to decide, maybe a bit of Nirvana, Coolio, Arrested Development, Ben Harper perhaps Eskimo Joe, Burt Bacharach - in the end I settled on some Pearl Jammy goodness.
This one was a close second.
And if you are talking shower singing who can go past this classic
I also have to share Caleb's favourite sing a long, except instead of Give you Hell, he sings Get you an Elf - so funny.
