Hi,
Esperanto Rock Orchestra ... used a lot of cellos, and their 3rd album has a great version of Eleanor Rigby with it.
Early ELO with Roy Wood, a lot of which was kinda taken out when he left the band, but his solo's are crazy with cellos, and I recommend them, though they can be unusual. Mustard is excellent, as is Eddie and the Falcons.
French band Wapassou also had cellos.
Right off the bat those are the ones I can think of.
