Does Greenwich North Tube station and Piccadily Circus tube station have lifts to platform?

Hi, I'm travelling to London and we want to go from Greenwich North Tube station to Piccadilly Circus - the Lyric theatre being our final destination. I understand we need to go Greenwich to Embankment and then change to Piccadilly Circus....are there lifts at Greenwich and Piccadilly? I have some difficulty on the escalators (mainly going down but I'm okay going up) and lift access would be really helpful. Thanks!
