Heh heh. Don't worry about never having heard of them - they're unlikely to trouble the chart all the while it's full of moronic tuneless dance tracks, identikit boy bands and other Flop Idol/Lame Academy types. It leaves precious little room for 'real' music. Ohmigod, hark at me. I'm turning into my dad. :O)
Anyway, The Sleepy Jackson are an Australian band, based mainly around the songwriting talents of their somewhat eccentric lead vocalist, Luke Steele. I think Lovers is their first full-length release, although there is a mini-album knocking about somewhere too.
The Beatles, you say? They'll never get anywhere with a name like that :O)
